After all the fees from closing and paying back the interest on the private loan my new loan was at 335k.

And, since we don't require reserves for this program, once we add in the 10% down payment, only $13,500 would be needed to close.

Of course, you can always contact a prospective fund operator directly and ask them your own set of DD questions (ask for their track record, properties that the fund has acquired thus far, performance of the fund, past funds that have closed to investors and how they have performed, etc).  

You will also have to factor in the closing cost for the new loan.

Most Heloc rates right now are around 7.75% to 10% so if you look at your blended rate between your fist and Heloc you would be better off doing a cash out refinance.A lot of people forget or simply do not know that if you do a cash out refinance the rate does go up but in 12 to 24 months if you do a "rate and term" refinance you can get it back down fairly close to where it was at prior.

Upon closing my single family construction my home had about 25% in equity on day one(in 2018 in Tennessee). 

Quote from @Allison Littman: I am currently trying to close on a church in Nashville (residential R6-A zoning) and convert it into my primary residence.

Open to ocean view, close to tourist areas by transit, farm ground or ranch land.  

After some additional research we have decided to focus on the aforementioned markets, but I will keep you in mind if we decide to look at Columbus more closely in the future. 

Congratulations on your impressive success since 2021—that's quite an achievement to have closed over 100 transactions in such a short time.
