Literally grab a few bags of steel wool from Home Depot or the like and tear off chunks until the gaps are sealed.

@Will GastonIf there is still live k&t, or any other old wiring, an electrician will want to rewire the whole house, for liability reasons, since they don't know where the newer wires end and the old wires start.If it's going to remain a rental, and to students, running raceways can be a way cheaper option than tearing out plaster.

Spoke to my partner last night and he is leaning more toward just tearing it down and put a new house on it.

They tend to leave the homes in disarray, full of trash and dirt as well as excessive wear and tear.

The building was going through several renovations recently, including tearing up and replacing the hallway carpets.

I know some investors are considering them just tear downs at this point.Should I increase my budget to $750k+ and try to find newer built homes or is it worth it to invest in these 100+ year old homes?

In its current state its a bit of a liability and safety hazard for tenants however I am wondering if there are some creative solutions aside from just tearing it all out and re-doing from scratch!

This means worst case scenario tearing out the kitchen.

Best case scenario, they cause more wear and tear on the property with each step they take, each pee dribble on the carpet, and the dirt they track in that accumulates to a stain.

Wear and tear on the car, gas, etc?
