Christian,It really all depends on buildable sq. footage, once you know that, you could assign a price of about $350-$400 per square foot. 

Even if the MTR strategy doesn't work for us, these houses still do well as LTRs, so we do have a plan B.If this works out, we'd like to continue purchasing properties utilizing business lines of credit for either the down payment or the entire purchase (more likely the entire purchase as the low price points make these properties difficult to finance with 15-25% down); I'm a traditional lender whose 100% commissioned without 2 years of said income on my taxes, so I'm ironically ineligible for traditional financing.

Done some research in different counties and found it will be quite hard to accomplish my vision if I try to build in traditional towns/counties due to zoning ordinances (might need a special use permit, could take months to years, etc.). 

I bought most of my houses through non traditional means.

When you say spend that amount of money as a broker, you mean selling them through an agent the traditional way?

So traditional thought would suggest 3 bedroom 2 bath units with 2 car garages.

Traditional mortgage.What was the outcome?

@Miyoshi A Peak, you keep seeing terms like "creative finance" but the reality is these deals are far rarer than traditionally financed deals.

I’m starting to understand why BRRRR is so valuable however I am confused on why you can’t borrow against you investment the same way in a “traditional” investment as you would the BRRRR method.

Inquire as to non-traditional credit items that don't show up on a credit report such as utilities, rent receipts, buy here/pay here car payments.
