Think about it, why do people do Airbnb........make more money, however they have higher vacancy rates, and more management required.  

While this won't stop the Gen Y and Z crowd, I think it will make it harder for people to raise money, when a company with 30 yr track records are marketing right along side the guy with 2 yrs (for a similar type of deal).

What the people that I talk to find is that they don't need to be confined to one area.  

I know many people who own real estate that are not citizens of the US.

Check your insurance, I’ve seen a lot of people specialize in renting to group homes or care facilities so there must be a commercial policy for this.

Some people will say to take on a processor, however a lot of them don't know what they are doing or they are overworked with other files and you still need to step in, or else you will do a poor job.. 

I tried FB ads, and got some inquiries but no bookings.It would be nice to have an AI program that would respond to people looking for a certain sized property in your location for certain dates.

You could give them a thousand bad reviews, if they are the only person in town offering a specific type of product, people will still do business with them.

There's a reason that people try to buy properties off-market and that is because you can find sellers who care more about terms than maximizing returns.So start with a conversation: you already presumably have some rapport since it's your landlord and you've spoken before.

You also want to go to real estate investor meetups to get reps with people who do what you want to do.
