So Congress in their infinite desire to never let a good thing go unpunished is putting the brakes on tax free primary residence sales and by extension house hacking in multi family structures. 

I'm not risking bringing someone else's parasites, pet dander (or worse), odors, or bodily fluids into my nice vacation rental.

I agree with Brian Ploszay “An algorithm doesn't have the correct inputs to make a decent valuation. “ the algorithm does not take into account the “inside” of the property, nor does it know of conditions in the local market or other fluid variables.

From a cleanup perspective, the biggest issue was fluids in the wood floors and joists.  

I did replace brakes after driving it about 10,000 miles, mainly because I was using the truck to tow a chipper... so more preventative maintenance than anything. 

On the settlement statement: the title company should list the purchase price and underneath that brake down of the rehab cost. for example: Purchase price: $55k + New Roof $10k + Fencing 2k + GC quote $15k (GC quote should be provided as scope of work) . 3.

Or Brake Clean.

On the very first day the new tenants, a group of three 24 year old stoners; I had to open my window and tell them that they weren't allowed to be banging on their brake rotor with a metal mallet at 11 pm.

I can't tell fully but it looks like Radiant Heating.They warm fluid and then circulate it in tubing that runs in the floors of the home.

With a lot of brains no showers, limited time for food or bathroom brakes you will be just like me.
