Good ole reliable.

Many lenders, including my group, offer a DSCR product to refinance on the back end as well.Before taking out a loan for a BRRRR project be sure to calculate all carrying costs (taxes, insurance, utilities, HOA, loan interest, etc.) to ensure (i) you have sufficient cash to cover monthly payments for at least the duration of the project and (ii) your estimated rent after repairs is at least 1.10x PITI (monthly refinance loan payment principal and interest, taxes and insurance).We have a proprietary BRRRR cash flow calculator tool that we share with our clients to help reliably assess costs and returns for these types of projects.

@Jeff StevensonYou really should consult a qualified professional or two, specifically at least attorney.So far, your lender is correct that legal entities, such as LLC's, are not eligble for conforming residential loans. 

Consult your local laws. 

Consulting with legal and financial advisors will help ensure your lending practices are compliant and secure.

The turn is an ongoing part of the business that you cannot always predict when it will happen, but you need to have in your rolodex reliable people who can do a workmanlike job for you quickly and not three months down the road.

In order to make educated judgments, market demand must be researched, high-impact upgrades prioritized, and specialists consulted.

Yes, I think my particular area it takes longer, or at least that is what the 3 realtors that I've consulted with said.As far as the loan, I want to tap into the equity rather than taking out a short term/high interest loan.

The attorney I consulted felt if I had closed then found the issue that I should collect full cost of the non-disclosure.  

I strongly advise consulting with a financial advisor or real estate professional who can provide personalized advice based on a comprehensive review of your situation.
