Being a Dad, combined with interests in energy efficiency and building automation led to a couple of small properties (triplex, quadraplex) ... which led to a few slightly larger buildings .... which lead to a second job {not quite big enough to outsource all the management}. 

Thus the more blunt instrument approach of using an IRR calculation and comparing it to one's cost of capital seems like a more logical approach to me.To each his own.

You will pay a modification or assumption recording fees linking the already recorded instrument to you as a borrower.

I have podio automations built into the site.

I then take it to my title company (the owner of the title company is an attorney) and have them construct the instrument that we are using and the note. 

Either of these instruments give you some protection.

I use guesty, and I've 100% automated all my vacation websites together with Guesty....it's such a nice thing to have, as I don't spend any time on my 6 listings.

Premium allows you to automate a lot of tasks like grabbing pictures of the property from Google, bed/bath info from Zillow, and lots of other things.I primarily chose Podio because, with Premium, I can do a lot of the automation coding myself and customize Podio to my needs.

It could be worth considering a shot at a rental property management software built for DIY landlords (1 - 15 units), and helps you to automate your own rental process (ie. helps you to get it listed on 10+ major listing sites, allows you to schedule showings, provides you with thorough tenant screening options, online digital leases, automated maintenance tracking, and fast rent collection which also offers your tenants the ability to report their positive on-time payments to the major credit bureaus; just another positive reinforcement/added incentive to get them to make those payments on time).

They helped us setup our systems and automation, facilitate transaction coordination, lead gen, and marketing.
