[In order to get another conventional Refi loan for all your $56K cost, (allowing that your lender might only loan you 70% of their valuation), sold comps would need to be in the $80k range].

I got a query from a new company called REX, a startup that says it only charges a 2 percent total commission fee because it cuts out the middle man by using artificial intelligence and other high tech to identify and market to the type of buyers interested in my property.

Would it be wise to use a HELOC to augment the $10k I currently have to get to the 20% down payment required for a conventional loan? 

You can charge 50% if you’d like.  

Most coaches charge a fee.

If the can go conventional you have a shot.

A "conventional, conforming" loan (from Fannie Mae or Freddie Mac, if you recognize those names) have no prepayment penalty. 

To give you some perspective, my lawn guy charges 25$ for my property that is down the street from you.

Its currently occupied and the rent being charged is way lower than comparable houses in the area.

So what you are publicizing to the rest of the BP community is that you are only worth a full 3% and will even charge your client more in order to get that?
