Views, location to attractions and layout of property can make or break you in a good location or not so great location.

Best bet is likely (not absolute - everyone's situation is different) is to look at a national lender or broker that has options in lots of states - its a great development versus 20 odd years ago, with technology, internet, places like this - can have access to many more options than before (local broker or lender thats it)

To gain investor confidence, ensure the investment property numbers are real, use the most common contract forms in your state (versus a 2 or 3-page) internet/guru contract form) with appropriate addenda, or an attorney-drafted form and attorney-drafted assignment agreement.

There are many options, so instead of me listing a million things, it would be more helpful if you could lay out a few options you're considering, and I can provide some feedback from there.

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

Also do not take documents off the internet, get an attorney to draft documents for you and also always close with a title company. 

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

My acknowledgement of investors seeming happy was based on internet discovery. 

I made the layout more user friendly, added a whole wall of closets in the main bedroom, totally gutted kitchen and bath.

If I was approaching this I'd want chatbot that used the ChatGPT language model but was closed off from the internet and only trained on my data.
