Now purchasing a home with cash is always good b/c obviously cash is king but also I think the part you might've missed is that, the money your utilizing on these home's won't actually be yours, but the banks or whatever institution you used to fix the home or make its value worth more.

Bank Lessons learned?

Most people don't qualify for that relationship.The seller financing will not show up or affect the credit score.However, when applying for a loan at the bank or especially a Federally Guaranteed loan, they ask on the application for ALL Loans, whether  or not it shows on a credit report.

In particular, the ability to auto-sync and categorize bank transactions (similar to Stessa), easily track expenses against budgets, and streamline lease creation with lease templates is quite nice.

I have used both Traditional (pre-tax) funds, Roth and HSA.

I've even been sitting in a bank struggling to get my LLC set and called my senior advisor attorney who called me back immediately to help out. 

In this manual (which I assume could be modified to provide to tenants) I include all the financing information (which you would not include for tenants) bank accounts, mortgage accounts, payment information, and mortgage payoff), a list of the contractors, what each contractor does, a list of upcoming planned or necessary repairs, and a copy of all leases associated with the property.

The bank they are using with that offer is now saying my site prep bid came in way too high and not approving me (so far. still in process).

We are still doing a ton of fix and flip loans there and the numbers make sense for the banks.

Regarding a HELOC, most banks will only provide a HELOC up to 75-80% of the property value, so you may not be able to access a HELOC for a while.
