Then there is a state like Colorado, where the bidding process is done by paying a premium.

At 599 total heated square feet, the small tiny home will feature an open driveway, 3 bedrooms, 2 bathrooms, kitchen, living and dining combo, all electric, with a full size washer and dryer.

You mention that its a SMALL kitchen and a microwave hood saves on valuable countertop space plus its an eye catching sizzle feature that sets you apart from comparable rentals. 

There are variations in design, features, upgrades and so on. 

Screen my tenants very strictly and rent in premium locations so that works best for me.

Back to the kitchens, I especially like the  (before) galley kitchen with the tile floor, and if there was a door opening at both ends at ADA specified widths that would be a nice feature too.Good Luck!

But once your property is ready to be listed, find a good property management software that has all the features you need - Listing Syndication, Tenant Screening, Lease Signing, Rent Collection, etc; and you should be able to have a much better work-life balance.

If your entities are disregarded, you may be able to have them within the same QBO and keep up with each using the location/business feature.

Sure, but I agree that until you really know your problems with scale you can't justify the cost of a custom or premium software solution.

Companies managing hundreds & even thousands of doors use Buildium.Many of them though, use a CRM on top of it for even more features: Leadsimple, Monday, etc.Look into Appfolio, Propertyware and RentVine.
