Do people just wait for tenants to give them checks/transfer rent or do we need to send a invoice every month to tenant for rent payment?

My town is quickly becoming a tourist destination and some people who prefer that it remain a quaint, sleepy little beach and surf town, are selling to move to more remote locations. 

But you will most likely not be able to get premium rates until you have a proven record in managing other peoples property.  

But if you want access to the benefits that people like me have contributed to, and collectively spent decades and god knows how many millions of dollars building, why would you think you should get access to those items for free? 

You need the right team of people to get things done. 

There's a lot of great people on bigger pockets that can give you some good advice when you need it.

They care about other things: ask people in hurricane, flood or fire-prone areas!

Pros could be: Clean water + tub for each guest; on a well, so no water waste concern; can make it design-y + cute; can be used winter (hot water) + summer (cool water); goes better with forest location of the home than a traditional hot tub might; will hold same number of guests as hot tub would (2 people in each tub).In researching I have seen some people on Airbnb have these checked in amenities as 'hot tub', some 'private hot tub'.

Because you used, "he" and "she" it appears you've dealt with 2 different people on this.

Clearly, those people can't afford that loan, so why was it even offered to them?
