As far as how much you pull out it depends on terms.

The "fine print" here is fairly sizeable upfront fees and high interest rates, relative to a traditional construction loan from a bank.  

No excessive fees upfront or during holding period4.

Tenant tries to deny it but he pulls out the wipes and shows it to them pull from the drain.

Especially in the "investor" areas, buyers are being more disciplined and we are able to pull some levers to get decent deals done for the buyer. 

In my devious mind, I thinking like you that I hire a parking attendant, install gates and charge an entrance fee if I bought it. 

However, with this in mind, contact the closing firm and ask for an escrow fee sheet to ensure that it somewhat aligns with the standard title/escrow fees that other closing attorneys offer.

As an investor buying rental properties, the buyer should never have to pay a fee to purchase something. 

My question pertains to impact fees. 

Only thing better would be initial deposit and then paid in full upon Certificate of Occupancy and punchlist complete.Of course, standard items should also be checked: licensed, insured, willing and able to pull all required permits, reference checks.I would also commonly avoid the cheapest bid you get.
