The question for me is what are real specific reasons WHY this is happening in S-FL?

We offer 100% financing on both purchase and rehab (loan size up to 75% ARV) but only in 10 states.So if the location and the numbers are right, you can be as low as 0% down.Yes, this kind of leverage does exist on the short-term purchase and rehab loan, and for reasonable terms.

Quote from @Caleb Brown: 3K flat fee is reasonable.

A detailed before-and-after P&L comparison would be useful here to show accuracy and weaknesses.I have a relatively sophisticated rehab spreadsheet I’ve been enhancing for years, and I know it’s reasonably accurate.

I've heard that a lot of realtors resent seller financing offers for some reason because of something with their commissions?

The reason I ask is at that rent point there is no profit on a sustained hold.   

If they've genuinely abandoned, you'll notice their clothing, personal hygiene, and things of value are all gone.

Quote from @Cooper Meurer: Lately, I have been mulling the idea of selling my primary residence and renting for 1-2 years before we leave the Midland area and move to the Texas Hill Country (surrounding Austin area)Reasoning for this:- I currently have around 120k in equity in my residence and I have a 4.75% interest rate. 

The reason why many lenders shy away from Manufactured Homes In general, is because there is not a lot of business for it for them to feel comfortable lending on it.
