Also lot of insurance companies to give new quote asking for proof of new roof replacement otherwise not giving quote which concerns me as my roofs are very old replaced by previous owner or original roofs. 

However, the dumbest part of the law is that you can't file for eviction until you show proof that the house passed the lead safe certification.

I mean material as recently as late 2022 was totally off-base-- the real estate rookie bootcamp, you had porfer Morby on here, the Carl twins that promote STR as recession proof, the list goes on.

@Ben EinspahrHouse hacking in Denver metro areas involves lenders reporting rental income on Schedule E, accepting 75% of STR/MTR income from lease agreements or appraiser's estimates, and requiring additional proof via tax returns.

Fannie Mae will allow you to count Boarder Income if you are purchasing a new Primary home, have had renters living with you for at least 13 months, have proof of receiving rental income for at least 9 out of the last 12 months, if you qualify for Fannie Mae's HomeReady program (which is an income limited program, you do not have to be a 1st time homebuyer to qualify for this program).

I personally never hear stories of the turn key provider spending extra sound proofing between units or investing in better quality fixtures or other high touch building materials so that the end buyer can enjoy reduced maintenance costs and better tenant engagement.

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.
