@Jon FletcherWhat the prior poster was saying is if you wanted a 90k loan On blockfi for example it will be 7.8 bitcoins.The crypto collateral you must provide is significantly higher.

Bridge loan.

(No mortgage on any).the cash flow is a total of $3,100 a monthDo portfolio loans exist for these kind of situations?

Does anyone know if loans are 90/10 or 80/20?

If you are considering working with them, I strongly advise you to double-check the provided rates and terms carefully.During my loan process, I discovered that they had added a yield spread interest without informing me. 

A quick internet search suggests that foreign national loans can provide up to 75% LTV.

I have preaproval for a 250K loan now.

You can only do this with a commercial loan.

My inclination is to suggest paying back the PML 70% of the land proceeds (presumably $168K) at that closing and then hold the remaining loan until I sell the house. 

With a 203k Renovation loan, you can also finance in your payments if you are doing a major rehab.
