My dad was left to pay and have his credit impacted drastically I have documented proof of all these happenings.

I eventually want to get into building 5-10 houses a year, building myself up to the somewhat more recession proof market (Im thinking $650k+ builds, I also really enjoy lakefront.)

You can make photocopies of the pages that show 3 different parties living there, with notation of the year and that will be proof that it was a triplex at that time. 

To claim these, you’ll need to keep detailed records, including receipts, the purpose of the meetup, and how it relates to your business, as the IRS requires proof that the expense is ordinary and necessary.

The presence of e-cigarettes is not proof they are being used.

Is this something my realtor should have looked into; asked about the POS report and either found out the sellers weren't going to fix things or ask for proof they were compliant? 

If you find proof that a plumber flagged this as a bigger issue, you could have a case that the seller was aware but didn't disclose it.Best of luck! 

In that case, if they can provide us with proof of contract cancelation, we terminate their lease without a fee and refund their full deposit (assuming there isn't any property damage).

(ask for the receipts )Proof)) ;-)

I am declaring primary residence but will live elsewhere as my lender only requires "intent to move in by 60 days" with no proof of move.Three units - $4200 rent income1st unit (3 bd 1 bt, ~1000 sq ft) is currently vacant, previously rented for $1600.2nd unit (3 bd 1 bt, ~1000 sq ft) rented month to month at 1050. can get $1600 as well.3rd unit (2 bd 1 bt, ~800 sq ft) rented for 1000 until April 2025. can get closer to 1200-1300.
