I know of 5 people who are in the hole due to various reasons.

A hole, a 3/4 inch hose and an electrical cord arent it!!!

If anyone could be so kind as to fill the gapping hole between my ears it would be appreciated.

15.5" diameter hole with an 18" diameter lip.

(And done correctly you get a lot of motivated seller leads) So why wouldn't someone create a website  The only business I am going to that may or may not have a website is my favorite mom and pop hole in the wall restaurant down the street, but I am only spending $10+ dollar, I am not a motivated sellers looking for a solution to sell my house! 

Nobody blew any serious holes in my thinking yet :)

An extreme airflow restriction of the return air will cause drainage issues, coil freezing(in severe cases), and poor cooling.

You are trying to fit a square peg into a round hole.

The home was previously bought with an FHA loan so I would think it would be financeable but trying to see if their are DSCR lenders who work with these houses before we start hitting up everyone and going down that rabbit hole.

Some examples of these are as follows.Exposed wires, holes in walls or incomplete walls, no smoke alarms etc.
