I live in the land of South Florida where the worlds most shady contractors congregate.In the past 5 years, I've lost in excess of $50,000 to thieving builders and handymen.

Now bear in mind, the excess cash flow will NOT be able to be credited to your  income.  

Great rental area where you can pick up a 3/1 for $35-$45k and get rents in excess of $800.

Robert, it depends on the time of year as to what a mortgage company does with the excess payments.

SELLER CONCESSIONSSeller concessions include, but are not limited to, the following:Payment of the buyer’s VA funding feePrepayment of the buyer’s property taxes and insuranceGifts such as a television set or microwave ovenPayment of extra points to provide permanent interest rate buydownsProvision of escrowed funds to provide temporary interest rate buydowns,Payoff of credit balances or judgments on behalf of the buyerSeller concessions do not include payment of the buyer’s closing costs or payment of points as appropriate to the market.Any seller concession or combination of concessions which exceeds 4% of the established reasonable value of the property is considered excessive, and unacceptable for VA guaranteed loans. 

Frequently, neighbors are asked to keep an eye on the house and know more about it than anyone else.So, in conclusion, zombie homes, probate homes, homes own by people with dementia, the efforts involved to locate these people to make a deal is far in excess of what you get in return, that I did foreclosure homes auctioned by banks, as when it comes up for auction, the banks is ready to sell it.

More than 4x seems a bit excessive for a rental criteria.

For the properties we currently manage, this vetting process has worked wonders in finding tenants whom take care of the property, pay there rent on time, and don’t require an excessive amount of attention.

"In the management of Your Property(ies) some amounts may be paid by a tenant or prospective tenant, pursuant to the lease agreement or tenant application, which will be retained by Us as further compensation for Our services, such as late fees, notice fees, non-refundable deposits, administrative fees, municipal service fees in excess of taxes paid, etc."

When you pay the property off you can use the excess proceeds to fund your next deal.
