The cash that would flow in a 30 yr loan underwriting scenario is sent back to the bank so that builds equity faster.Forced appreciation, while excellent overall, I am not sure it helps in this situation to avoid income from cash flow as that will probably both provide equity, but also increase cash flow right away.

I know some mentioned about developing banking relationships and I totally agree with that, so here is what you do. 1) Open a business checking account in the name of your LLC to hold the assets. 2) Deposit your cash into that account to fund the real estate purchases3) After owning for 60-90 days, talk with a local lender about a line of credit against the 2 properties at 60% LTV. 4) After about 30-45 days, have the line open to use if you need that liquidity that you used, but until then you are not paying 7% interest on nothing.
