I firmly believe that most small landlords don't get nearly the returns they think they do because they don't accurately track their actual income and expenses. I've run the numbers on a lot of small residential rental properties and just can't come up with adequate projected returns to offset the additional risk of them unless you go into less desirable areas where properties are still cheap - but then of course you're taking on even more risk. I've been interested in residential real estate and just don't think the numbers work for me. I use the stock market instead, low cost passively managed diversified index funds.
Residential rental real estate has a rule of thumb that 50% of the market rents will be eaten up by operating costs. Some people will claim to beat that, but looking at their numbers in detail will tend to show overlooked or disregarded expenses (ie, "I self manage so management is $0" when really you should be accounting for that time somehow) or front end loaded expenses (they spent $50,000 renovating the unit so repairs are low, for now, but will come due all at once in 10 years). When evaluating a specific property the 50% rule may not be enough but it's good enough to get you started.
I put together a spreadsheet years ago to evaluate residential rentals and I just kept coming up with a real return of 5% - 8%. That is right around the real return of a stock market index fund and not enough to entice me. Any higher returns came with properties with big question marks or a lot more work than investing passively.
Many people will say to bank on appreciation, but to me you can not count on anything beyond matching inflation. Housing price growth in general may surpass inflation, but only in specific areas and - here's the big one - only in owner occupied properties. Rental properties tend to not make the jump from rental to owner occupied; they tend to sell to other investors to use as rentals, so the market and pricing for them are completely different than that for owner occupied properties. The reasons for that are varied. The finishes on rentals are lower grade (otherwise you're losing money renting them out!), the maintenance is different, they tend to be in less desirable locations than owner occupied houses, etc. Another big one is they're often sold with tenants in place and you'd never get an owner occupant unless you empty the unit first before trying to sell it - and of course that means zero income during the period where you're trying to sell it.
I'm certainly not saying nobody makes money on residential real estate. There are some that do really well with it, but it takes more than just buying the first house you come across and putting it up on Craigslist for rent. At least that would be a learning experience, though!
On rental commercial property, which is my day job, the work is different, risks are different, and returns can be terrible to very very good. I think SVreX has it right on the nose for the market right now - small owner/operator businesses have a terrible time finding reasonably priced well maintained commercial rental units and when they do find it they will stay for as long as they can. Your eviction requirements are much looser than residential but then again so is your leverage. Loans are harder to get, and terms are less favorable. We do office space and tenants are beyond pleased to have an actual human they can talk to that has the power to say yes or no, and that cares about the property and businesses there. We don't lose tenants to landlord issues, we lose them to growth (we're full so no space to grow into) or market issues. Then again, that style of management makes this a J-O-B and not a passive investment. On that front, commercial management is pretty easy to find, but I don't know how to find *good* commercial management since we've always self managed. Generally there will be a local coalition of commercial real estate brokers and you could can find references there or through BOMA, https://www.boma.org/ the Building Owners and Managers Association. Expenses can be breathtaking on a commercial property just due to size. It's not unusual to have a $100k roof, or a $50k masonry restoration job, or the like. So you have to either have large maintenance reserves or a really good line of credit. A property like SVreX has recommended has advantages there as you can stipulate that all in-suite maintenance is the tenant's responsibility and the landlord is only responsible for the exterior shell of the building. That can lead to some shabby interior work being done but whether that bothers you is personal preference. It would drive me crazy so we have it to the point that our tenants call us for everything - sometimes even stuff like hanging TVs. Which I love to do so I'm happy with that! It beats finding 20 holes behind a TV mount after they move it later, too.
Sorry for the novel. I could go on, but this is a lot to chew on for the moment. Any thoughts or questions yet??
Edit: I forgot to add - land as a real estate investment for the small guy seems terrible to me. Zero income, only expenses, total gamble on if it will ever be worth even what you paid for it much less more. Land investment is the zillionaire's playground. They can afford to buy millions of dollars in land and sit on it for a decade or two in the hopes that one or two parcels will pay out big. Leasing to farmers is a very low income, isn't it? I've never seen the case for the average person to be able to make a reliable and decently sized income off of land investment.
