Recently decided, to invest in a mobile home park but sold at a loss.

It's a small place so I'd guess it won't rent for enough to cover your expenses anyway so I'd probably sell, especially if the loss is small, it unless it's in a great neighborhood that you think will do well over time. 

I’ve been in contact with the Better Business Bureau about them  cut your losses and go the other way. 

This kind of investing is usually short sighted and focused only on immediate returns without taking into considering long term vision and investment.Excellent point about trying to put Class C tenants into Class A properties and vice versa.The first one will create lots of vacancy, deferred maintenance, loss of rental income, increase in evictions etc. 

Or just looking to offset the loss?

That amounts to a loss of $6240 in cash flow per year.2) Property Tax discount of $466 per month is for the first year. 

I can see the OP giving this a shot.. but it is risky he could end up making a few bucks and getting experience might just break even or he could take a loss.. that margin is very thin in markets that are not selling as soon as you get CO  thats been one reason we have been profitable very few homes have been carried past CO so financing cost are at a minimum.. you hold a spec home 6 months past Co and every month your losing money you will not recover.

However, as W2 earners, these losses are considered passive and can only offset passive income unless you or your spouse qualify as a Real Estate Professional (REPS) by meeting the 750-hour and material participation requirements or STR is used.

Thanks to this equity growth, we were able to recover much of our initial cashflow loss.

I am left feeling that working with them was a wasted investment and decided to cut my losses and move on.
