Your niche depends on location and amenities you offer.

I would just search your area and add "real estate investors" or something along the lines of that

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. 

I have been reading the online resources about getting started, searching the market, and even doing tours, but I am hesitant to jump in and buy a house as I have quite a large amount of student debt.

@Mark G.We tried cold calling and that didn't work too well...with Propstream you just use your search criteria and it will give you a list of prospects to reach out to. 

They cut out all but the best locations and were way more cautious.

You're buying a specific property, in a specific location, in a specific condition, subject to local rules and regulations.

I do it manually (and keep in mind, it also depends on the state and location - VRBO does for some and not for others, Airbnb does for some and not for others) I know many folks happy with Avalara though. 

@Vincent WeselakIt’s a good idea to get an estimate for your insurance costs upfront since this can vary based on the property type and location, and it’s a key factor in evaluating your cash flow.
