If talking to more builders does not work out to join you on transaction #1+ and you have enough capital and heavy rehab experience along with a GC / builder doing the project many lenders out there will offer you a lower leverage loan for your first project on your own.  60% finished value and 75% LTC is probably achievable without a builder in your company for the loan. 

Be careful with that BRRR stuff.I personally would not do Remote BRRR as there is just a lot of risk with 1) risk of embezzlement with contractors 2) change orders and 3) bank doing bait and switch doing a lower appraisal and/or LTV on the refinance.Most service providers net worth is under 500-1M net worth and I just did not feel comfortable working with them because they would screw me over when I wire over 30-50k checks to do work.

In addition even with a lower down payment you should be paying significantly less per month even with PMI then you would if you moved into a single family house that you where fronting the entire bill for.

You can get into a home with a lower down payment and a lower interest rate.

As the deal size gets larger, this should get lower. 

The leverage is a little lower and rates may change, but a DSCR is still possible provided you qualify.

Instead, you’ll report it as lower rental income on your Schedule E.

This made sense when I could lower my interest rate and still cashflow on the investment property I refinanced.

If you are wanting to rent yours out, maybe look on Airbnb for others for rent in that area and price yours lower than the others. 

If they had $200,000 in cash they might do a higher interest rate MM but have it tied to a loan to get a lower interest rate on the loan, but a higher return on the MM.
