Even though you can't write off loss against your W2, you can carry over loss from year to year.

The sellers are most likely selling because they do not work, and therefore they would be unwilling to carry a note on the property.

I never got an answer, but my assumption at this point is that it WOULD carry over.

How do you sell a mobile home park without having to carry the note, and for the highest possible price?

They carry a note while you fix and make payments then... when the property is ready to put on the market and once you sale then he will transfer title and you profit 

Few companies carry them, i.e. credit insurance, but I worked in one company that had it.

I'm sure one can get carried away if they aren't mindful of those expenses.  

now if you live in market and its your day job to manage your lower end rentals and you self manage or can assist the PM in real time.. it can work we see a lot of mom and pop landlords on this site that are successful or at least they say they are.. but the one's that are honest will tell you its not a bed of roses and these lower end rentals carry risk.. 

I don't use one as we have one STR, but I carry a ton of insurance.

I understand that it might be tough to sell a small park outright without me carrying the note, for example 10-20 lots.
