I am also selling an apartment complex and I recommend finding who is doing it and connect with them.

The other townhouses in the complex and area are over $650k for the same size and square footage.

I am meeting with the owner of an 8 unit off market complex tomorrow.

It does not directly offset it, the mechanics are complex, but you should benefit from the $50k losses, resulting in no additional taxes from the sale.

Creating these complex structures from what I have experienced only costs me time and money and potential issues down the line to make sure documents are signed by the correct people and entities etc.

Investors are buying the property in the area and have bought the apartment complex next to my property and several houses down.

You can get up to 10k PENALTY-FREE which is 10% on top of taxes.If you use a Self Directed IRA (SDIRA) you may be able to use the 9k as a down payment but I would argue this is going to be more complex, especially as a first-time investor.

My partner and I are currently trying to work a deal with an investor to purchase an apartment complex.

I had to repave a driveway for an apartment complex.
