So are you saying the Mortgage One deal would be the way to go? 

Hedgefunds, large buyers, mortgage companies etc. 

Once each cabin is built we would like to take a mortgage out to recover our cash and then use to build the next.

@Jonathan Blanco, I'm and investor and a licensed mortgage broker so I've been on both sides of this conversation.I would look for a lender that (1) listens to you and understands your strategy and needs (hint: it's not always money), (2) has experience working with clients executing your strategy and brings more to the table than just cash - be it advice, relationships, deal-team partners, etc., (3) gives you viable options and explains the pros and cons of each option and (4) you enjoy interacting with - this should be a relationship, not a transaction.Once you find a few lenders like this (and you should have relationships with more than one), then you can start comparing rates and fees.

I'm a mortgage broker, so need a wholesale lender. 

We had to save up the 5% to get our first place with an 80/15 first and second mortgage.  

They aren’t able to get a mortgage themselves so they would provide the money while the mortgage and deed would be in the others name.  

- very low remaining mortgage balance!!

Mortgage payment is approx $1800.

They acquired the exiting LLC and mortgage.
