The only other alternative is to have something known as the “sale or disposition of business property” that gets reported on Form 4797.

You may be able to negotiate price or interest rate to make the deal more attractive, but I would certainly negotiate the term of the loan beyond 5 years. 

I was using Avail.co to list my 3rd rental property. I decided on them because of all the options for listing. Turns out that they do not have access to Zillow Group anymore and apartments.com even thou they keep mark...

I get the sense that this is not your recommended way to go about this problem :)  Do you have any alternative advice? 

What am I doing wrong to attract a lender? 

Alternatively, I can close the prop from Builder’s Mortgage using a primary home ARM.

You have to rollover those funds into self-directed IRA first, then you can invest into alternative assets such as real estate and more.

Also utilizing rehab stores like the Restore can help as well as looking at alternative construction materials. 

(we are starting to explore alternative financing with out team, and I'm trying to dig into the rules & regulations but I'm not a pro by any means)The numbers on the deal are STELLAR and we'd hate for it to slip away if we can work or overcome this snag!

Are there any alternatives for pulling money out of equity in this case?
