If you're looking for the cheapest route, conventional may be a better bet.

The debt may not report to your personal credit (unless you are late on or miss payments, then all bets are off)2.

I bet the rate of Engineers going homeless is all but 0. 

In the last few years, they've made illegal:-Rent controls of any kind-Limiting of fees or screening charges-The ability of HOAs to regulate STRs or LTRs in their neighborhoodThat's just the start.

if you are going to do things like include utilities, or have an off street parking spot, other amenities etc, there's no reason in my mind you couldn't "charge a premium" for a premium unit/service. 

I would reach out to experienced PMs, landlords, and realtors in your area to see what others are charging.

Not many landlords buy their rentals this way. although with all the guru training many are trying and we will see how it all works out.it takes sales skill to talk people into deeding you their home.. this is a highly charged emotional situation..

We also use Rental Guardian and add the charge to each booking so essentially the guest is paying for their own damage insurance.

They don’t charge anything for these extra accounts, my tenants pay directly into those accounts.

Then I have a credit card to charge supplies and any utilities which allow credit card payments.
