I'm eager to grow my book of business in various markets and connect with active wholesalers.

In many ways, this is the best market for buyers in Austin in years.

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

While @Phillip Austin mentioned Raleigh is a higher returns its just very much a appreciation market, you will not find rentals that cashflow, so depending on your goals its a good or bad market.

It sounds like mistakes were made on the properties but I'm also questioning the market (you didn't say where these are). 

I have a lot of good information on the KC multifamily market that I can send you. 

Does anyone from you know how can we market a SFR available for lease for retirement homes?

Or find a deal first then market it to buyers, then offer on the house and create an agreement with the seller & buyer?
