@Daria B. if your MD gross income exceeds the thresholds in this link, then you have to file a non-resident MD return. 

She wants 150000 (I'd offer less due to some repairs that need to happen) and the gross monthly income is about 2100.

The apartment is 16 units. 134,500 gross and 100,000 NOI It's located in NY.

@Michael Green, not sure if you mean gross yields or some kind of total return? 

FYI, I start with gross income,  then subtract vacancy and collection loss to get to effective gross.   

@Spencer GrayBased on some of these online calculators I’m hovering around 9-10% cash on cash return if I use the example of 135k down payment 62k gross income 26k annual mortgage payment21k operating expenses 3% vacancy loss Thanks for the feedback I’m horrible at math but 9.8% is the number I got when I plugged in all these numbers.

I tossed in the percentage of business as many commercial leases have a gross sales component but if that were to trigger UBIT I would explore something different for that element. 

The tenants keep the room clean and set up schedules; prices are set at 1.75/ea. it brings in 280-320 dollars per month gross which meets my criteria easily.

The Gross Rev from AirDNA on this property is $100k gross / $71k NOI which has proved accurate with our other STR 15 min away.

If your monthly housing bill costs your tenants more than 1/3 of their gross monthly income you are asking for defaults.
