Taxes in PA are generally cheaper, so your holding costs will be less. i do not know anything about Leigh Valley, my properties are in Central PA. there are areas where houses are only worth 50K and areas where houses are 500k and up, so you have to study the area, maybe there is someone in that area here on BP that can help you more in that area.

There are a number of factors to consider; how long your brother has owned it, value of the property, type of building and specialty options (charging stations for electric equipment, etc.), fencing and security systems, and numerous other factors.

It's a cheaper interest rate as well.
