They have clear photos of what the tubs are, so there is no confusion, + according to reviews guests seem to love them as a hot tub experience. 

You can drive one hour a month to drive by and ensure the place is still standing, or ask your tenant to send photos.

You should also invest in a professional real estate photographer and a lock box) You may just decide to go with an agent that can provide professional level photos and an amazing marketing package (including listing exposure in real estate magazines, etc) If you do go with an agent- make sure to ask for their marketing plan for the property as well as a record of their past sales, etc.

Are their listings detailed with good-quality photos?

That enables you 10% nominal anual returns while it's still very liquid (fast and easy accesible cash).If you want to invest into real estate, why don't you look for seller finance or rent to own deals?

I go to his Facebook page and also notice that it says he works for Keller Williams so I ask him if he does in fact work for KW because about seven Frank Walkers pop up on realtor.com but none of them have profile photos or are in Texas. 

@Eryn Garcia  I agree with @Eli Kantor  the hot tub instructions with photos really saved us a phone call at one short term rental and that is saying something since my husband can figure most things out. 

With this bank, they only required time stamped photos to be submitted to prove their was no damage. 

As for returning the deposit if there was clean up, hopefully you took photos of the condition of the home once it was vacant and have an itemized bill to present the former tenant.
