So the market is equally important when considering a self storage acquisition, and you need to underwrite it with ALL of the expenses for the facility, not the 3 expenses the seller shared with you on a scratch piece of paper. 

At first they simply asked for proof of transaction, ok easy, printed off a paper with me signed in showing the specific dollar amount sold and withdrawn to my checking account.

You should get to the point where you can run the quick and dirty numbers on a property in 15-20 seconds without a pen and paper.

I may try my hand at a flip someday, but for now, I'm happy just flipping the paper.

Let them spend the time to bring thought to paper.

On paper there are a lot that look great, but I don't have any first-hand owner experience there.

I didn't want to spend the time to deal with local realtors / rehabbers / tenants (or out of state one for that matter) because I couldn't handle the stress of late night toilet/tenant calls and I didn't have the money.  

This is between you, the young woman and her boyfriend.Personally, I hate when tenants view a legal contract such as a lease as nothing more than toilet paper.Gail

I will stick to paper checks then.

Same would apply to flooring: if I found that the flooring beside a commode had a higher moisture content compared to the same flooring at the doorway, that might cause me to conclude a wax ring has failed or a supply line has failed behind a commode.For mold to be present, we first need cellulose (wood, MDF, paper, etc).
