I don't see any reliable apps that focus on handling maintenance requests for small multifamily owners (2-4 units).

Rental demand has been strong with an asking of $1,700 per month per unit that does not include utilities.

That said, I'd recommend focusing on locations with high sales volume as you will have more options to choose from in these locations.So far this year, 240 multifamily properties (2-4 units) have sold in the Bronx - Source OneKeyMLSThe neighborhoods with the most sold properties are:- Wakefield and surrounding North Bronx neighborhoods (31 sold in '24)- Throggs Neck and surrounding Southeast Bronx neighborhoods (31 sold in '24)- Pelham Gardens (30 sold in '24)- Pelham Bay (28 sold in '24)These areas account for 50% of the recent Bronx multifamily sales... focus here to have more options!

Photograph or video the empty unit and get the place ready for the next tenant.

Best of luck.Dimitrius Kiritsis hit it right on the head, if I had to add anything from my experiences, learn what a CAP  rate, NOI ROI is in your, of course you'll need to look at rents for similar size apt units, I say the main thing is knowing how much the property is bringing in and how much is going out.

How many units or homes are you managing?

My lending entity (i.e. my LLC) has a bank account at a national bank. 

We paid for some FB Marketing for leasing up units in our apartment. 

I have been investing in Single Family and am now looking for multi-family 10-30 units.

I want to create a duplex up unit by combining the second floor and 3rd floor into one unit.
