I know they might be easy to borrow from, but you might want to look at more professional funding sources in the longer term.

The first thing a borrower should do is look at the lender / broker's reputation.

The borrower has a SFR, the are renting out to a tenant, who is running a Adult Family home/ Hospice operation.

It’s a straightforward way to access the funds, though keep in mind that interest rates may be higher since it’s a rental.Alternatively, you can consider a HELOC (Home Equity Line of Credit), which gives you flexibility by letting you borrow against the equity as needed, similar to a line of credit.

if you borrow from one property to pay for another you're just losing money and pretending you're not.  

Nobody worries about the $65k I just paid in legal fees to finally get ownership of 2 properties that the borrower hasn’t made a payment on in almost 3 years!  

The borrower is a long term hold borrower. 

You don't need a formula to borrow funds.

The issue that I'm facing now is whether I want to pull it out against one of my rentals or on my primary.I have found a bank that will allow me to borrow as a second lien on rentals but their rates are higher than what I could get when just doing it against my primary.What I'm most worried about is what happens in a worst case scenario, should something drastic happen in the market.From what I understand, using the money against a rental doesn't necessarily provide much more of a safety blanket in case things hit the fan because if, somehow, the HELOC lender can't recover their money, you'll get sued anyways.

I have a small local bank here that closed a Heloc on a borrower's current primary residence while she was in the process of closing on a new primary residence.
