- Am I able to do a mortgage assumption from personal to the LLC to avoid the balance being called and effectively keep the interest rate?

Appreciate some feedback.I had a tenant, ironically also in Gaithersburg (hope it’s not the same person because she was a pain in the *** lol) but she wanted a new carpet we paid half, she paid her half via us uppping the rent $50 over what it otherwise would have been, so that’s always a creative option, however I wouldn’t want gas at my property if I could avoid it, always a risk of a leak or worse so I’d probably lean towards saying no to this specific request.

Do you earn appreciation on the note or claim depreciation on your taxes?
