It's not just the quality of properties that make a neighborhood good or bad, it's the quality of the people who live and hang out there.That's why you or someone you trust needs to go there and get a feel for it, whether it's your Realtor, your relatives or whoever.

It sounds like your relatives thought they were doing you a big favor, where you could make money on it as an STR. 

MUCH more affordable than installing ducted systems and would probably be a good, cost effective strategy for your relatively small cabin.

This can be both protection to you and your relative holding the property if there will be jealousy involved as you won't personally be identifiable so there won't be family "drama".  

If you don't do this, there will be a lawsuit and your relatives won't be your friend anymore.4. 

However, the downpayment amount is higher.So there are certainly options here for your relative depending on what he/she is doing, can qualify for, etc. 

You don't have enough money to purchase a property that large and being a partner in that size deal is impressive when you tell all your relatives and friends.Here is the problem with being only a limited partner in that 100-unit property.

did I mention talk to your lender before you try to make a deal with your relative?

.assuming that you will need a loan / financing  to acquire the  first prop- I would recommend that the three of you  get  a  loan pre approval  for a hypotehtical  transaction  completed  in order to  determine if you can obtain a loan... as gifting funds  isnt allowed for investment  property purchase - your relative will need to be on the loan as well ....however you decide to split the  profits  (and to  cover the additonal costs ) - make sure all  scenarios are  formally  addressed  in writing  ...it might be worth meeting with a real estate  type  attorney  familar with  investors 

Given your relative lack of experience with hotels, consider aligning yourself with an expert or very experienced hotel manager when presenting to lenders.
