We still have no idea.

DSCR Loans - Both Purchase and Cash Out Loans- Investors typically use these on the cash out portion of the BRRRR Strategy - Minimum Downpayment, usually 20% but some lenders offer 15% down - Max LTV on Refinances, typically 75%, but some lenders will do 80% - Minimum Title seasoning (since the property was purchased and recorded on county records) is 90 days, although some lenders have no seasoning at all as long as you can show rehab work completed. - 30 year fixed terms - Usually have a Prepayment Penalty from 1-5 years, although you can price out a 0 PPP for a higher rate or fee- Minimum Credit score is 650 usually, although you could do a lower LTV loan at 620. 

Beyond real estate investing, BiggerPockets Money has great episodes on how to avoid the middle class trap with your investments - ie how to structure your investment best so that they're not all locked up in accounts with penalties until you're 65. 

Many real estate investors opt for a fix-and-flip loan because they’re relatively easy to obtain: no personal income verification (no DTI requirements), and you can often borrow up to 90% of the purchase price and 100% of the rehab costs.

I assume you currently have a residential mortgage that does not have a pre-payment penalty.

That means no more spreadsheet. 

Been there, done that, no thank you.

It is our full time job (so no other W2 job for us).

So you better find something that cash flows or you’d be better off putting the money in a bank CD. 

The "Initial Filing" is extremely important to get this right the 1st time as there are limited safe harbors for mistakes to avoid the penalties.
