What terms is he offering (monthly payments, amortization, balloon, etc.?

Bridge Loans are short-term (usually around 12 months) at a higher rate and fee to get a borrower from one point to another.

I’m particularly interested in methods that have worked well for you in terms of finding deals that aren’t listed on the MLS.Thanks in advance for your insights and suggestions!

Tenants don't get to dictate terms.

A refi makes more sense if you plan to hold the property long-term as a rental.

I tell people to start by picking a strategy (OOS long term, OOS short term rental, fix and flip, etc) THEN pick a market and submarket THEN look for good tools/people, doing it any other order tends to be an exercise in futility. 

I have a w-2 income and own three properties, all long term rentals, that I've had for a few years.

I wanted to help them out and minimize their loss and saw an opportunity to get a property slightly below market because of my commission savings, immediate mortgage and maintenance relief, in addition to keeping a lower short term interest rate How did you find this deal and how did you negotiate it?

Off-market deals give you control over pricing, terms, and creative financing options.

But I think they may still beat SFR in terms of cash flow there.
