@Josh Caldwell and @Jeanni Prescan i just settled a property this week where there was a holdback (an escrow ) set up to cover PA State Inheritance Tax liability, and I had another one two weeks ago, so I've had money taken from the proceeds on two settlements in two weeks going to Dept of Revenue for PA Inheritance Tax.We've also had hundreds of settlement, where the owner of the PA real estate lived in another state and "assumed"  that since they weren't PA residents that they didn't have to pay the Tax. 

What we read over several blogs is,1. if we have to take out plumbing and electrical permit, we have to have a building permit2. if we ourselves take out permit then we are responsible for all the work and insurance etc.I will definitely call the building dept

Nope, as a landlord, I want to choose who lives in my place and hold all the cards.And if I wanted to share the cards with someone it would be a PM with a business and insurance, not a person wanting to make a profit by raising the rent above market rate. 

But home insurance is very expensive in this state.

Then move into yours and take the now tax free proceeds from her sale to buy something in WA. 

What kind of insurance should I get?

Sell the house and pocket the proceeds.

Have you folks checked with your insurance company ? 

Also, you'll need to consider the property taxes and the home insurance payments.
