For your first fix-and-flip, the best deals usually come from motivated-seller channels like on-market price drops, distressed MLS listings, wholesalers with real inventory, and direct-to-seller leads, PPC leads.

We have a 3 bed 1 bath which we will be adding a second bath after our tenants move out. i have listed the place as 3bd 2bth.

My bookkeeping firm (100% of our clients are REIs) has a list we recommend.

Found a few in Reno recently and helped a buyer purchase a triplex at a 7 cap for $665K last year and resell at a 6 cap almost exactly a year later recently (link to Zillow sold listing here: https://tinyurl.com/3n6p6sf7). 

As a commercial GC, I provide all prospective clients with two lists.

The longer the list the better! 

How about broken assignment chains, paying attention to BPOs where agents filch old pics from the MLS and never visit the property, not reading the collection notes, not having boots on the ground check the place out, not using social media to stalk the borrowers, letting your servicer set the collection plan, not being up the servicer's behind...and the list goes on. 

Theres properties Ive got hundreds of thousands off list price....there are others where the properties even with significant days on market sell at 99% of list price. 10% off though, lets say a $1 million property...10% off is a pretty big number. 

You can't list your commercial rentals on their website, it is definitely geared for residential rentals.   

Look for any listing over 1 year old.
