That "saved" the partnership $165,000 in liquidity.

Would you recommend BRRRRing & increasing my interest rate on my 1st home or not Refinancing that home and liquidating 1/2 - 2/3 of my stock portfolio to pay for the down payment of the 2nd home?

I mean...at the end of the day, isn't this all about cashflow and liquidity for expansion? 

Some people call them "Bank Statement Loans" as what is required is usually 2 consecutive months bank statements showing enough liquid assets to make down payments for acquisitions.For refinances on rental properties most hard money lenders are looking to make sure the property cash flows, or "DSCR's".

You're going to need at least 300-400K liquid to get a 2 family in prime Brooklyn.

I have a new investment through a business partner that guarantees a substantial return along with the principal investment so trying to liquidate what I can and what make sense for the time.

SFH typically appreciate quicker, have lower interest rates for the loan, better quality residents and are easier to liquidate.

Larger apartment complexes and multifamily buildings aren't as common, and demand for rentals is usually pretty strong.The major issue you may run into in the future is if you get a larger portfolio, it will likely be a long and painful process to liquidate should you ever decide to do so, since putting ten or twenty houses up on the market all at once in these communities would probably add 30 - 100% to the available inventory, greatly reducing their potential sale price.

I'd rather not have to liquidate anything to pay the down payments/wedding if possible. 

In short, buying REITs are very liquid.
