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

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

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!

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.  

@Chris KellyFind an on-site 3rd party to corroborate.

I don't advertise anything at all and never have in more than ten years on the site.

Quote from @Arvand Sabetian: Does your lease state you're providing internet for the tenants?

There are a lot of shiny internet companies touting their HELOC, but you will do better with a local bank every time.

Can any of you make some recommendations on how we can install cameras without possibly having to use an internet network?

If you can rehab your way into a house-hack of a small multifamily and live on site, I think that would allow you to improve your cash flow by getting a short-term rental license even though the city is making it harder to do STRs.
