And leasing is still unheard of.

I was able to close all my properties within 30-45 days which is basically unheard of.  

Property taxes at 12% is unheard of I think

It's not unheard of but it needs to be in the loan docs.

An expense ration of under 20% (12/62) is virtually unheard of even for new construction.- I do not see any expenses for property taxes listed.- Again, because the time period of the expenses is unclear the insurance is suspect. $4,760 / 24 is a bit less then $200 per unit.

The transactions my company is doing are not unheard of, but they do require someone who is willing to actually look at the entry and exit of the deal, as some would be bundle purchases with a systematic unload.

It's not unheard of for Sellers (Wholesalers) to not want to pay the commissions, but perhaps talk to someone who works with these sellers on a regular basis.
