Agent gets paid from the net proceeds unless the seller is unwilling to pay the buyer agent fee/commission, which in this case you do not have an agent; that agent would ask (if they were representing you) for the buyer/you to pay them their commission from a buyer broker agreement (if the seller was not paying commission).So it's the same difference, the seller will pay it (2%), and the agent will not come out of pocket for it.

That makes sense that the lenders would want skin in the game, but what I'm wondering is for a 60k-80k total deal, it seems like lenders are wanting 40-50% of the total loan.

I do not hassle people with having to sign a separate agreement.Vrbo allows you to upload your rules and the renter agrees to these when they book.I just type my rules in the Airbnb listing. 

I've done it for single-family residential.

Really the person that is going into the flipping game should know the market very well to do these comps on their own, and back it up by asking their trusted real estate agent/professional for confirmation.

Andrew, thank you for all of the great feedback, it gives me a lot to think about and look into!

I am exploring the possibility of purchasing an off market plot of land, building a modular home, and then selling it.

.: @Owen Rosen I'm in WA as is STR Do you have an agent? 

It gives you one property that can potentially pay for itself while putting a roof over your head and giving you experience as a hands-on landlord.

We definitely want to be aware of those...We would love to come see your current projects.
