With 65 units, I have a revenue manager who is checking it daily. 

Using AI ;-) the answer is ""Detroit has approximately 102,330 vacant housing units, which is 28% of the city's total housing stock."

I had listed a 10-unit property in Cincinnati, OH, and found a buyer through an agent from a different office.

Today, I used those proceeds to purchase a 5-unit commercial retail building without coming out of pocket at all.

Consider using an FHA loan to secure a 1–4 unit property with just 3.5% down and take advantage of tax benefits by living there for at least two years.

I'd estimate that there are less than 1,000 legitimate, or "professional" wholesalers, in the United States of America, as defined by individuals who make $100K flipping contracts, and collecting assignment fees, in any form, and who have made that amount of income more than 3 years in a row.

I have them on several units and no issues.

Many of these are low income, government subsidized housing units.

Now, in 2024, we're seeing $4,000 per month just on the main unit and $1,800 on the other unit of the duplex.Long story short, it's a long term play.

I will be quick to admit I have only had experiences with small rentals (6 units and smaller) so if you are looking for help on larger apartment complexes I would not be a great resource.
