I was able to get them in touch with an off booking sites place that had an opening in town.

So a community of these homes could definitely provide an affordable downsized housing option for active seniors (independent living style) - especially when you provide amenities on site, which will be required if you want to compete with other independent living style communities and apartment buildings.

These things need so much power that unless the site has access to major grid access point you're wasting your time. 

One thing people haven't mentioned is look for your own ad on the key rental syndicated sites and see if it presents well. 

What are the metrics for determining site selection?

Here's a few examples:Does the lender release for materials on site or do they have to be installed? 

Would love to get rid of all the spam on the forums but the site is geared towards new investors and service providers; so, I am not the target audience.

Their customer support is terrible and some of their software, but they have about 8x the site traffic in general than Airbnb and VRBO combined, surprisingly.  

I mainly want a site that offers advertising the property, online payment options, maintenance requests & at least a basic accounting aspect.Thank you in advance!
