If it's a good deal (by 2019 standards) go ahead.If you do some research on last 5 economic recessions and home values you will find that the last one was the only recession where home values crashed.

As soon as you see no signature line, no website you can go back to and check out, no clue who the company is or where to find (geographically) them, it doesn't matter how hungry you are, how good your deal is, you are about to go on a horrific journey that will sideline your real estate investment career for some time while you spend all the energy you intended on real estate investing, on damage control.

The AC market is ripe for investing, and there is so much growth happening economically in the city.

Also you get warranties, the house is going to be more energy efficient reducing the utilities for the remnant. 

Real estate is very local.All economic recessions are different though. 

Maybe your energy costs are substantially different.For each unit to feed electrical, you'll have the cost of copper (usually 30A - 40A wire at minimum) to feed a disconnect, and then the cost of the disconnect, and of course the labor.With economies of scale I'd think you're a little high, however this totally depends on your application. 

If not during due diligence you should be getting a (PCR) property condition report outlining potential deficiencies and items of correction needed.Look at location of Dollar General with traffic counts, sight lines, access, population growth levels, income levels, crime reports, school systems, economic development department plans for the area, etc.If building is obsolete but rents are really low per sq ft and sitting on a nice piece of land then might have some upside in redevelopment in the future at higher rents.

Also in an economic downturn or recession when money is tight vacationing is the first thing to go so while a often a VRBO can have great cash flow it may not withstand an economic downturn as well as a regular in town rental.

I do believe in appreciation in Pullman as well as the city and other agencies have been facilitating economic development.  

My house is vacant now.i am looking for tenants what is your advise about screening a tenant.Any economical way of screening?
