My wife and I own and self-manage a portfolio of rentals in the Western Washington area (some BRRRRs and some traditional 25% down conventional financing) and use cozy to manage all of our tenant sceening, online rent collection, etc. 

You can literally find answers to all of your questions within the confines of this site.

We have listings with good pictures and a description on zillow, cozy and craigslist.

I am new to this landlord thing I am on my fourth property and its all sink or swim now.My second property which is a newly acquired vacant, is a duplex small 2bdrm apartments 500sqft each yes really smallI want to make up for the crampness and make it cozy I was thinking because I can tile pretty well to tile the whole floor a lot of work up front but less effort on the back end.tile replacement is rather easy as long as i keep a few extra boxes in the attic.or crawl space. as a compromise I can carpet the bedrooms and just tile everywhere elsethe bathroom and kitchen already are tiled. cost wise I dont think I am too much beyond good laminate or vinyl flooring or my cheapest hardwood. tile is only my choice because I think I will get a really nice look. which may attract a better quality tenant.

I've listed on facebook marketplace, Zillow, and cozy which pushes it to realtor.com, trulia.com, and a couple others.I've had a lot of responses from facebook, but 99% are dead ends after pre-screening.

17 SFHs, 1 LLC, 1 checking account, 1 umbrella policy, 1 Excel spreadsheet, 1 Cozy account. 

I am planning on going with Cozy to help.  

Not sure why you would confine yourself to just looking in mobile home parks for mobiles, unless you find it attractive that the home is already "situated" and doesn't have to be moved.

I quit my cozy salaried job of 3 years and we started our real estate company, Building Appalachia.

Cozy allows them to do this and I don't pay anything.For my other tenant I use the bill pay through Quickbooks.
