If it's nice inside and out, or can become nice, it could appeal to travel nurses as well.

Just for numbers sake, there are some YouTubers doing 10,000 calls, 10s of thousands text messages and 10,000 mailers a month.

You'll typically find that travel nurses want a 13 week term as that is the most common length of their contracts.

If you figure it takes a few thousand to build a new bathroom, but you can charge an extra $50 for that room.

You'll end up with a dog that you can't unload at the end of the day when you've dumped thousands of dollars into it with no positive return. 

It's one thing to say that "a typical tenant would likely stay for X years" and another to say that "on average, across our properties and thousands of leases, we see that tenants stay X years" -- the first one is a bit of an assumption and the second one is a stated fact. 

The target demographic for MTRs is traveling nurses.

They billed me $200 plus thousands of dollars. $2 was only down payment...

This has saved me hundreds of thousands of dollars.

The rate will be higher (typically 1% to 1-1/2% higher) but you will be able to sell, refinance, or payoff the loan without  having to worry about paying what could potentially be thousands of dollars in a pre-payment penalty.
