If you served you can go into the VA.gov site and look for your COE and/or apply. 

We used a combination of Wayfair, thrift stores and online second-hand sale sites.

I also really like RETipster's site.

One more tip – people remember stories that trigger their emotions.

I am typically looking at larger more expensive items.What I have typically done is once I am officially owner of the property, I will ask each tenant to name me 1-2 items that need to get repaired/fixed/remedied right off the bat.

My go-to site is Ingram's Water and Air Equipment. 

This site is the primary website that travel nurses use to find MTR's.  

Yes, management is more intensive, and 50 units is nearing the size of facility that having a small on-site manager could be a benefit for oversight, management and leasing.

There are lots of options like VRBO, booking.com, direct booking platforms, snow bird sites and medium term rental sites. 

If you look through many of the threads on this site you will see a great deal reviews showing full experiences that encountered obstacles, but more importantly, how we stayed involved to resolve the issue when those issues came up.
