Now it's chart-making time. We list the subject property, and all the other 
properties, at the top of columns on a page.  On the first line under the 
heading, we show the  asking prices of any of these properties that are up 
for sale. On the second line e write in the recent sales prices, if  any. 
On the third line we show the value we've temporarily assigned to the subject 
property. We leave this line blank for the other properties. Why? Patience.
We've said that you wee walking through the various properties, sizing up the 
desirable and undesirable features of each. Now we list those features on our 
chart. We make this list as sketchy or detailed as we feel like, bearing in mind 
that we're interested only in features that could have a significant effect on 
value.
In other words, the important differences between the properties are what go 
into our chart. If the quality of kitchens varies sharply from one building to 
another, kitchens would certainly be one item on the list. Contrariwise, if all 
the buildings provide about t he same parking facilities, you might decide not 
to bother listing parking as an item.
The differences you think are important should be listed won the let-hand 
side of our chart. Next we grade them for each property: "A" for excellent, "B" 
for above average, "C" for average, "D" for below average, "E" for 
unsatisfactory, and "F" for  non-existent.
Now we get into numbers. Dollar numbers.
That is, we make the shrewdest estimate we can as to how much each difference 
is worth by comparison with the subject property. Afterward we'll simply add or 
subtract all the value differences to get our bottom-line estimate of how much 
more or less each property is worth than t he subject property.
To see how this works, let's take an imaginary situation and  work out 
the analysis of comparative value. To keep things simple, we'll assume that 
we're comparing a subject property with only two other properties, and that all 
three are so much alike that we notice only five differences significant enough 
to jot down.
The subject property, we'll say, recently changed hands at a price of 
$200,000. We assume - just for purposes  of our analysis - that this is its 
fair market value. The other two properties are currently offered for sale at 
$195,000 and $205,000, respectively. We write this basic information in the 
appropriate spaces near the top of our page.
Then we turn to the first item of major difference, which might be the 
bathrooms. Those in property no. 2 all have two washbasins, gorgeous ornamental 
tile, fancy gold-plated fixtures and faucets, and other glittering features we 
wouldn't expect in that neighborhood. Hard to beat. So we write an "A" after 
bathrooms in the column for property no. 2. By contrast, the bathrooms are about 
average in the subject property, so we give them a "C" in that column. In 
property no. 3 the bathtubs are cramped and the toilets are inconveniently 
placed, so we figure they rate only a "D".
Now comes the question of what these differences mean to the relative values 
of the three properties. To get the answer, you must estimate how much it would 
cost to upgrade the bathrooms in the subject property to the quality of those in 
no. 2. You can make your own estimate or, if you have absolutely no idea, you 
can consult a contractor. Just remember, you don't need to pinpoint the figure; 
somewhere in the ball park will be enough for our purposes.
Say you come up with an estimate of $1,200 each. This would mean a total of 
$3,600 o fix up the three bathrooms in the subject property. You write a plus 
$3,600 under "A" rating you gave the bathrooms in property no. 2. Using the same 
reasoning, you might guess it would cost $3,100 to make the three bathrooms in 
property no. 3 as good as those in the subject property - so you put a minus 
$3,100 for the "D" bathrooms there.
Onward! Next item on our list is kitchens. Below average in the subject 
property? They get a "D". In  property no. 2 the kitchens aren't as classy 
as they might be, but we'll give them a "B" because the equipment is newer. In 
property no. 3 they've all been remodeled lately. The rate an "A" because 
they're as up to date as any lady could reasonably expect.
Now the numbers again. How much would it cost to make the kitchens in the 
subject property as modern as those in properties no. 2 and no. 3 respectively?
You decide it would cost $1,900 (mainly for new equipment and cabinets) to 
pull the subject-property kitchens up to the quality of those in property no. 2 
- and about $4,000 (including extensive remodeling) to put them on a par with 
those "A" kitchens in no. 3.
We ran through the other items in the same way. Swimming pool? The subject  
property has one. The others don't. The one pool is just about average for that 
part of town, so it rates a "C" and the other two properties get "F", of course, 
on the line for swimming pools. How much would it cost to put a similar pool in 
t he  yards of no. 2 and no. 3? Maybe $12,000. So we write a minus $12,000 
under those two "F"s.
Apartment heating system? We've noticed that the subject property's units are 
chilly on a cold day. But the other two buildings' heating can keep anyone cozy. 
So we rate the subject property "E" and the other two "A". Let's write a plus 
$4,000 for each of the latter, because a heating-system contractor tells us it 
would cost about that much to bring the subject property's system up to par.
Maybe the final item on our list is storage space. Okay in the subject 
property, truly spacious in no. 3, woefully cramped in no. 2. But wait. There's 
an unfinished area in property no.2's basement. It could be made into three 
good-sized storage rooms at a cost of about $5,000. So we give no. 2 an "E" and 
a minus $5,000. We have to award an "A" to no. 3 but we have far more storage 
space than ay normal resident would need. Subject property receives a "C" 
rating.
So now it's a bottom-line time, the moment of truth. We simply add the plus 
and minus figures in each column. The answers tell us how much more or less 
properties no. 2 and 3 are worth than the subject property. The we can add or 
subtract these amounts from whatever value we tentatively penciled in for the 
subject property, and the answers give us a guess at the value for the other two 
properties.
Having done all this, we still can't be sure that the bottom-line figures for 
no. 2 and no. 3 are a good guide to their fair market value. They could be way 
off, if the subject property recently sold for much more or much less than it 
was really worth. Furthermore, there could be cases where your subject property 
hasn't been sold lately, isn't being offered for sale, and  thus gives you 
no fix on what it might be worth. Even so, the analysis tells you that you'll 
probably be getting a better buy on no. 2 than no. 3 if you grab them at their 
respective asking prices. This is the main reason for making the comparison. No 
matter whether you arbitrarily assign a value of $1 million to the subject  
property, or $1,000, you still end up with an idea  whether property no. 2 
or no. 3 is the better buy of the two.
If you need a more accurate reckoning of how close your figures are to fair 
market value, you can fine-tune them by including additional properties in your 
comparison - properties that have been sold lately. The more actual sales you 
consider, the closer you'll come to figuring fair market value.
In any real-life situation you'll surely consider more than the five 
categories of difference we picked out of the air for our fictitious 
comparisons. One important category will probably be the relative square footage 
of the various properties. This alone could make a surprising difference in 
their potential worth.
Square footage is important, because, for one thing, you'll have to 
heat it. Fro another, you rent space. People prefer spacious rooms and closets. 
So if one building has more usable space than the others, tenants may be willing 
to pay higher rents there.
Total square footage can fool you, though. Even though one building covers a 
bigger area than another, it doesn't necessarily contain more rentable space. 
Maybe the supposedly smaller building has outside patios with each apartment, or 
outside walkways between apartments. And maybe the "bigger" building has all 
inner halls, which of course must be regularly painted and cleaned and carpeted 
although they don't put a dollar in  your cash register. In that case the 
"bigger" building probably has higher maintenance costs, and its actual rentable 
space - meaning potential for revenue - is smaller.
Step it off, use a tape measure, get the blueprints, do whatever you prefer - 
but know each building's square footage of rentable space. Start with its total 
floor space, then subtract footage that won't produce any income. That gives you 
the net space that will bring in all the rent money. If you know the current 
rentals you can compute the amount of income per square foot - a useful 
yardstick in comparing properties.
Some unrentable space can be made to pay off in other ways, perhaps. Maybe 
you can put in laundry machines if the building doesn't already have them. Or 
how about vending machines? Is the complex big enough to make their next 
revenues worthwhile after deductions for installation, servicing, repairs, and 
depreciation? Maybe you can install a coin-operated telephone in a hall or 
lobby, of there seems to be demand for one.  However, these possibilities 
are irrelevant just now. At the moment, you're trying to compare and evaluate 
each property's current condition.  Its net rentable space is an important 
item for your checklist.
I wonder if you're thinking, "Wow! This is an awful lot of comparing and 
figuring!" Sure, you'll find it tedious the first time. Bt what's a few hours or 
even days of your time, compared with the thousands of dollars you may be able 
to save?
Even if you don't follow through with a purchase, making these close 
comparisons will give you valuable experience. Each time you do it, your 
analysis will be faster and easier. Soon you'll find you can get a feel for 
relative values of properties just by walking through.
