A pretty common way is to go through a private lender.

Hey Luke - Tapping into your equity through a HELOC is definitely a common way to fund a down payment, but like you said, having two open loans can lead to higher closing costs and potentially impact cash flow.

They are a young engaged couple, and we actually have a few acquaintances in common (a connection we discovered when they were moving in). 

Probably not the most common opinion around here, certainly not the sexiest. 

On the MLS (whether via an agent or via Realtor/Zillow/Redfin), so that's where you need to be.Scenario 2 - A homebuyer looking for a primary:  This is most common (except maybe in vacation markets). 

That 10% below market value is what I've commonly seen the last couple years.

This is all too common and you aren't the first person to be told this...

Simple, the MTM tell them they need to go, I am not certain of PA laws, but I think a 30-day notice is sufficient, and or cash for keys 

You gave the required notice within the 30-day period.

Me and my partner were wholesalers and noticed that there are a ton of FSBO homeowners that dont want to use agents but the issue is Zillow pushes these listings to the bottom.
