And this would be attractive because if they have cash laying around, you'll give them a better return than it's making in a savings account, CD, etc. 

What type of renter do you think it will attract? 

Usually, provided all the units are attractive, you would probably get more total rent. 

I'm a new RE investor in general and my intention was to shop around here if anyone is wiling to offer a better rate than my current one.I mean no harm/offense to any lenders out here, but I thought it would be a 'fun' post to do to attract some attention and traffic.

Probably not.Consider adding amenities to attract guests and raise your prices to fit that level of quality, but keep your guests number limited to less.

The research, vetting tenants, property management, repairs already done, etc. is attractive to a 1st time Rental investor. 

You can get by with just one, but 2+ is certainly attractive to renters, particularly short-term guests.

For such a community, I think pickleball courts, walking paths, and dock access to local waterways would serve as enough incentive to attract homebuyers but not incur high HOA/increases to retail price. 

For one, they'll attract better quality tenants, which makes vacancies, tenant turns, servicing your debt a lot more likely and less variance to when you go to lower or middle class tenants.

The less attractive view and smaller units get very close to your example numbers and sell all the time.
