Flip side, for a third of that you are trained to find properties using creative finance taking over existing low interest loans that cash flow and you are buying in decent neighborhoods with every day lunch box Joes that have kids and go to work and pay rent on time. 

If you make decent income the deferred income can be substancial but you have to do something with those funds; As a part time real estate investor that's where the SDIRA comes in handy.  

A $100-$200k down payment would get you a decent multifamily property, possibly with land depending on where you look. 

If you want to nestle into North Scottsdale, you can get the big house and a decent lot, but it will not be a huge lot. 

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

That is the decent (and courteous) thing to do, so that others won't spend time to write an answer, and so that others who search out an existing topic can see that answer.

The second challenge would be finding land in a decent enough area where building a rental makes sense.

And someone jumping into this as a complete newbie can expect that they have a decent chance of making some expensive newbie mistakes.

But if you get a major expense you could then potentially have a decent amount of debt.
