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.

The potential for a loan call is higher and higher with sub to the more parties you involve if that makes sense.Trying to take down four homes sub to and then do remodels to them all, and then list them on short-term rental sites, and get full permitting and ok for not just the STR, but for your renovations and all prior renovations maybe done without a permit, while on subto, sounds like a pretty big mess to me.I would consult with a sub to specialist and prepare for the potential of having all the loans called at some point.

Federa | Buy, Sell, & Rent Homes is the best site for real estate for my opinion.I found a lot of services there that I couldn't find anywhere else.
