And my lender is great with fix and flip rehab loans - and their a bank so the rates are comfortable.  

You might need to get with a credit union or smaller local bank bc to get $70k for repairs will be a huge stretch.  

I hear that the banks do not like to finance mortgages under $100,000. 

I heard the same thing: all that is required from foreign nationals is: EIN and US bank account.

That house appears to be undergoing foreclosure from the bank. 

Banks will not lend if they know you'll be losing month every month, the deal needs higher rent.

EXEMPTIONS Real Property - The sale, lease or rental of real estate (land, houses, buildings and other structures attached to the land) to the same person or occupant for thirty or more consecutive days.Intangible Property - Sales of intangibles (copyrights, royalties, notes, bonds, etc.)."

Unless you have a crap ton of properties its fairly easy to just update the numbers once a month by logging in to your banks website and copying over the new principle balance figure. my excel simply shows property address my estimated value, the debt amount and calculates total equity. 

Looking at a Multi family project and the bank is willing to do 15% down however not with a Solo 401k due to the non-recourse loan requirement. 

I’m considering calling it quits and doing my own research and offers directly with REO/ bank owned websites like Home Path, Bank of America, City National etc...
