Sure. But what's your need/aim/plan?
I'm in the same boat plus add that I need a place to live. I've been out of RE for 12+ years and ended up living with a friend as her caregiver. She died in July and I'm scrambling for a place to live as her father is getting rid of the house (which I can't afford and don't need the sf). Add that I'm on social security and a small pension, and that defines my needs ...
1) an affordable place to live ASAP
2) passive income to increase my monthly income
So I am looking for both. FSBO to make purchases more affordable; preferably properties with some kind of income - so far looking at SFR with a MH or RV pad on acreage; SFR with an orchard & fruit stand on acreage; SFR with an apartment and 2 greenhouses on acreage; a fixer 3 plex (not livable so on my remote radar; a 4 plex expired listing that's in good condition but 50% vacant (due to remote location???); 4 plex with 5 RV pads (not licensed and not likely to be any time soon; realtor advertised it as 4 units and 5 RV spaces so 9 unit became a 4 unit when I checked state licensing for the RV spaces - just a follow-up - she didn't like my 50% offer for 50% vacancy).
Short term rentals are management intensive - make ready on every move out, immediate fixing of problems, need to be in perfect shape (can a bad Yelp review ruin your business?), etc. That said the rents may be higher, but so are the expenses. I would wonder if insurance might be substantially higher than normal landlord insurance (thinking about the tenants who throw big parties and destroy your property). Plus you probably will have occupancy tax (like hotels).
Vacation rentals are like ST rentals, same types of issues.
Ditto hostels - full time staff though probably some bartering.
Ditto Bed and Breakfasts - I hear complaints re never getting a break.
Sort of ditto on mobile home parks and marinas - but each can have onsite or offsite management and then you'll have to manage the managers.
Apartments should have a property manager to shield you from tenants. (think 2 am clogged sinks) but benefit from more units under single roof; easier to find property managers for more units; higher income and more income opportunities (vending, laundry & parking & storage income).
Corporate housing is interesting - usually higher rents, all inclusive (utilities usually included) and everything paid by a company for longer than normal rental terms. (1 I looked at in NM $1800/mo rent included everything - elec, gas, cable, internet - paid by a hospital for a doctor doing elective surgery for 15 to 18 months at a time plus laundry income. Market rent for the 2b1b 700 sf unit would have been maybe $725.)
Flips - assuming you mean buy, rehab & resell ASAP - gives you ordinary income (highest taxed income) rather than capital gains. And you probably don't get the benefit of depreciation ("phantom income"). Unlike monthly rental income, the profits will come when you sell, so not a way to increase your monthly income. You also don't get equity in the long term.
Buy and hold gives you several returns - if you buy at a discount to market value, you get instant equity; as you pay mortgage; you get equity as the loan goes down; you get monthly income from rents; expenses and depreciation will probably put you at $0 taxes; and eventually you'll get capital gains on sale (assuming CG tax rate remains lower than ordinary income which is no guarantee with a tax happy administration).
Anything you do, you should plan on succession from the outset. Buy in an LLC or at least a trust (living or land trust) to avoid probate issues and to make the property more sellable (is that a word?).
So what is your plan?
