Speak with an accountant and/or 1031 exchange intermediary to find out exactly how much you would save from a tax perspective.  

If it is under the house the structure engineers wearing white shirts and ties who worked in the air conditioned office aren't interested crawled under the house.

As a matter of fact, that's exactly what I am doing.

The guy who was interviewed did exactly what you are talking about...bought a couple of single family homes and rented out the rooms which helped him to be able to continue buying more rentals.

I have the same exact scenario happening now with a referral I made to Florida.

They are of all different sizes, conditions, number of bedrooms, some are in foreclosure, some are on auction, some for sale -- and all of these different qualities make it hard for me to compare.

I can buy a house in good condition and which is current on the mortgage, with little equity using "Subject To" and make a ton of money.

If I am only going to wholesale the property to another investor as soon as I buy it, do I have to have the exact repair costs or a repair estimate?

But, this is the exact type of question I would refer to my escrow officer, regardless if I even had common knowledge. 

It looks like it is in rough condition from the outside, which may be why it is still listed even after 6+ months.
