Hi Steve, glad to have you as a part of this awesome community!

and why are they needed in this deal?

This article presents three key factors to consider before deciding that now is the time to sell/exchange: 1) regulatory, 2) economic and 3) personal timing.1.

As someone who is new to real estate, I'm thinking of being a bird dog for investors (although I haven't found any to work with me yet ) until I learn more of real estate. 

.: Anyone with experience (and/or referrals to lenders) with non-recourse loans?

The thing I'm trying to do better with going into the new year is handling receipts. 

As best as I can tell on both sites, the algorithm looks something like this:Cheapest price>least restrictions (cancellation, # of days minimum, etc)>Premier/Super host>Review Scores>Most discounts (weekly, last minute, etc)>Regular revisions

Looking to see how I can tell if a vacant lot/land is allowed for a single family home (SFH) or duplex to be built on it.The area is West Palm Beach, Boca Raton, Ft.

@Seidy Lasker Wash sale rules apply to stock options if they are deemed "substantially identical" to a security sold at a loss within 30 days, such as options with similar expiration dates or strike prices.

@Dennis Bragg this was solid advice.
