You will need to qualify as "real estate professional to do so" Which simply put is spending 750 hours in a real property trade or business, and more time in that line of work then anything else.

I always thought pet odors needed a bit more, though, such as taking care of the subfloor.

I'm not a tax professional.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Some people love them and actively seek them out while others don't care and would spend money to convert it back to normal. 

More general advice, sorry for not getting too specific, but careful with how you frame your direct mail outreach. 

If he is working full time on real estate you’ll qualify as real estate professional for tax purposes.

Because they don't care about cash flow, they just care about long term wealth building and wealth preservation.

Having gone through the process once, it's very clear how to keep growing for the next one :) Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?
