Hello BiggerPockets Community!

Community that will not lose value, but possibly gain. 

Cold calling is a great idea to get started, but maybe try connecting with local real estate groups or online forums too—they can sometimes have off-market deals.

There are more factors than just the community (#beds, level of theming, location to the amenities, style of home (single family, townhome, condo) and others) But I would strongly advise to stay within some of the same communities you mentioned like Storey Lake, Windsor Hills, Championsgate and a few others if cash flow is your goal.

I personally use Quickbooks online and have a virtual (remote/nonlocal) bookkeeper.

Call a different number you found online associated with the same company, etc. 

Paterson, NJ Hi BiggerPockets Community!

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.

Most of the "Sub-To" community members I've met on the journey are the most overzealous people in the game.
