It is a 3/2. 

Knowing PA you can get yourself in some trouble if you change the lock before the tenant moves out even if it is written in the lease.

I just bought a Minut to put in a unit where I know the tenant is smoking cigarettes but I have a tenant that we ALWAYS see smoke his cigarettes outside yet when we go in his unit it stinks like marijuana.

Commercial brokers/agents do this on every deal. 

The window has to be big enough to climb out of and there needs to be a ladder to climb up from there or else it will not be legal and you could be liable in case of injury or death.If the basement has a walkout to the backyard on the same level that can work, but most will rise and fall by the above.

Due to a significant spike in demand, housing prices have skyrocketed, making it nearly impossible in some areas of the city to find solid returns as a real estate investor.

Now I am a certified real estate appraiser.

Do you have the lot in mind already?

I guess it's just in their heads? 

It's a great way to learn about your LOCAL market.
