I see 3-5 as a fad.Fractional ownership - way to much overhead for these to be profitable. think "timeshare".STR in non traditional markets - running a STR is a business and real estate, boils down to location location location - who would want to go to a conference and stay in a STR vs. the hotel where the conference is at, most businesses pay for this I do not see why.Mixed use with green - this has been going on for years- it will continue but it is also more expensive to build - which means higher costs to use.Not trying to be debbie downer, I have seen these attempted to be done in the past and they really have not been successful.I do really like the BTR model though as I continue to see that as a very good option in the future. 

Personally, I prefer to target tenants with full vouchers, as they won’t have to pay anything out of pocket. 

You can even "pay yourself" the cleaning fee if you want to and do the turnovers yourself. 

I currently pay a premium price for my turnovers for a local cleaning company that specializes in STRs.

There is a "sponsor exemption" but that only allows an unlicensed person to raise money but it cannot be more than 50% of their duties and the pay they receive cannot be based on how much they raised.If you have never raised $, a family office will be off the table as they typically want the company to ahve atleast $50-$100M in assets. 

Earning 25% is better than paying down a 5% mortgage. 

When you say professional quote do you recommend just paying a trusted contractor to do a walkthrough or do you first recommend getting an inspection to figure out what’s fully wrong/needs to get fixed before bringing in a contractor?

As those prices fluctuate, there is a builders somewhere putting his feet up waiting to see a market turn more active because the last thing he wants to do is start paying crews to build houses, that could drop in value while he's halfway through the build process and losing equity halfway into the project.

@Ryan Fox I would be paying attention to new cracks in the foundation.

Regulation will say you have to be registered and pay hotel occupancy taxes, but your unit may not qualify for registration.
