Are they putting down money as a down payment and do they have a primary residence they realize they could also lose if they do not pay you (depends on state). 

Get the primary under your belt.

Who is your primary customer, what is your RevPAR, what financing terms are you looking at, who is running the daily operations, are you looking to get under a major flag, i.e.

I currently own a duplex and a sfh (my primary resi) on the south side of Chicago.

That being said, Zillow is also the primary site in my market for rental searches, especially SFRs, so I have no shortage of tenants seeing my listing when it is available.The one downside, which is minimal, is even though the tenant pays rent through Zillow on first, and I get a notice that rent was paid, it can take 5-ish days to arrive in my bank account.  

I have 1 SFR  that is paid off and my primary is also paid off.  

For example, suppose your primary residence, rental properties, and employment are all in the same area.

See if you can get a copy of The Millionnaire Real Estate Investor by Keller.The Slight Edge and Atomic Habits too.Awesome board with many smart people having own suggestions and ideas to grow wealth!!

It seems in order of increasing profitability:LTR < MTR < STRGiven that I'm based in the Denver metro area, unless I'm occupying the property as my primary residence, STR is out the question, as Denver has cracked down on the short tern rental laws.

We also sell some of the duplex as 1/2...so sometimes it is listed as duplex, the pictures make it look like duplex, but really it is 1/2.Another strategy might be to buy 1 with 5% down, live in it a year, then move to the next one as a primary and use 5% down and repeat as long as you can...and of course if the numbers work.
