Remodeled a house before that had several animals as pets in the house (dogs and cats both) the animals were not let outside to use the bathroom (from what it looked like ever) we sanded down the hardwood filled a pump up sprayer with the odorxit (super contracted stuff mix as stated in bottle) sprayed all of the floors till they were soaked with it then opened the windows to let it all air dry.

Should I put in split air for ac/heat? 

Its good to have a crawlspace vented, but less than ideal in winter time when air is dry anyways and cold because you are trying to heat your house.

It's a split level that I bought in original condition, including a 1984 ancient-looking air conditioner and all the things that come with a house of this nature.The plan was to do a full cosmetic + replace HVAC and Roof + prune back 60ft tall pine trees AND turn it into a house hack bnb.What I've learned so far....- Trust but VERIFY everything on the buy side.

Consider replacing central air at the same time if you have it.

When I went into the Air Force and was stationed in Idaho I started a painting company and had 8 painters working for me while I was a plumber in the Air Force.

Because our area is super expensive to cash flow from buy and hold I see many investors doing flips and mid term rentals as well like air bnb or leases under 1 year.
