I don't have a large enough sample size to use my numbers as gospel.

But I don't know the size of the property or the condition.

That is hard to see - here is full-size image link: http://s17.postimg.org/xnsdd8zgv/model.jpg

Came across a house someone is trying to get rid of in Oklahoma City (May and 10th area) but I'm hesitant on doing anything with it because of the size.

Make sure you have plenty of pictures and documentation.Also check your local and state laws for how long you have to return the deposit or provide an accounting of any portion not returned.

So in your example, I'm going to make the following assumptions:10,000 income (was vacant for 2 months - actual rent is $1000 per month6,000 mortgage payment2,000 HOA1,000 utilities during vacancy period6,000 depreciationOn your tax return, you don't actually get to deduct the principal portion of the mortgage payment, so your loss will be something less than 5,000.  

The storage unit for sale is cheaper price than competition, some sizes by 10% and some sizes by 40% cheaper.The unit for sale is 65+ units, i counted only 4 units that were not filled, two units double locked.  

Send a copy of that portion of the lease and highlight it. 

What are you finding are the cap rates for those sizes of MFRs?

The unit cost describes, for example, a quantity of two dumpsters 8-yards in size picked up twice a month.
