I love this thread!
This post is more geared to multifamily evaluations and not single family.
Appraising single family residential is fairly straightforward. Value is based on what retail end/users are currently paying.
So, it’s just a matter of knowing market rents and assuming a self-managed, 40% overhead. If the house will break even against those assumptions, then it’s investment worthy (long term).
Anything else, and it’s a speculation, and in another category of investing.
Meantime, for multifamily, where the GRM’s are actually useful, there is another weaknesses in relying on them, or even static expense ratios, and that is, every property is different.
If the rents are substantially lower on a given property, the GRM may seem abnormally higher, especially if the seller is basing his price on newer, remodeled, or just better-performing properties that have sold.
Also, a 70-year old building with a boiler, common hot water and heat, will have higher overhead than a building that’s fifty years newer. It’s not unusual for a depression-era project to have expenses that run more than 70% of the gross scheduled income.
That’s why we need to compare apples only to apples, regardless of what valuation method we use.
The most important thing in evaluating income property is to use actual comps to compare data. And part of that is knowing:
- Market rents.
- Prevailing vacancy factors.
- Per unit prices.
- Standard expenses.
This goes for single family investing, too. Except that single family investors never use CAP rates in their evaluations.
Those figures are too susceptible to hiccups.
One stolen air conditioning compressor can skew the CAP rate on a rental for more than two years. One stolen compressor in an apartment complex is ‘business as usual.’
Meantime, everything else falls from one’s knowledge of the market.
For example, not knowing market rents, and the GRMs only expose gross ranges in value, but hardly a precise valuation.
Also, a high GRM could mean the rents are say, “$200/unit/mo below market,” but if we didn’t know that, the high GRM would scare us away (or help us negotiate a better ‘steal’… It works both ways here!!!).
That’s an extreme example, of course.
The only way to know these things is to actually know what similar units, in similar conditions, with a similar age and construction have in common, and what ‘should’ be happening, etc.
I think a fantastic way to really become an expert at making evaluations of property, is to deliberately analyze 100 property data sheets. It makes little difference what we analyze.
Half way through this process, and we’ll begin to spot the clues to the hidden bargains, just by recognizing the spreads between what the expenses should be; what the scheduled rents could be; and what the management costs can be. It’s magic!!!
Good post.
