I used the funds to acquire real estate that appreciated signficantly.

Estimates and projections are great, but experience gives you the real numbers!

Quote from @Aj Green: Quote from @Gregory Wilson: The real issue is how much of a deposit do you have to try to get back from them.Sure, your contingency might work but I assume you gave the deposit to the seller.

It’s awesome to see you starting your real estate journey so early, congrats. 

Hey@Briley Roe for my most recent real estate deal (brrrr).

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

Hey @Preet Oberoi, so a tiny home like you are describing isn't real estate but more of an RV.I would get with a CPA like others have said to get the skinny on the deductions.

I am a commercial real estate broker with an 81 unit portfolio for sale in Richmond, VA.

Every real estate investment is unique, and you're strongly encouraged to consult with an attorney to ensure your specific legal needs are properly addressed.

Your client should consult a real estate attorney to draft an agreement with the ex and ensure there are no legal or tax issues, especially since this is an investment property.
