You can 'tie it up' by making a formal offer to purchase, in writing, and then having seller accept it.

Since you won't actually be living in the property (and likely not doing your own formal inspection) you want to make sure you don't get sued for something that the buyer finds wrong with the property after the sale.

Now I own the property and would like to evict this person who is not able to pay rent.Do I need to hire an attorney in order to go through a formal eviction process or can I just ask this person to leave since she told me that she would not be able to pay?

That puts you in a suit fighting for reinstatement and a judicial foreclosure.

@Wayne Brooks - Pennsylvania is judicial, so no trustees. 

In this particular instance the tenant took a lovely open-plan 3 bedroom house and secretly walled off the formal living area to create an extra bedroom for his kids.

Meaning, they want to formally partner with an LLC and are looking to find an equitable way to split expenses, revenue and equity.

Based on my experience though buying homes in Canada for my personal use and lending money.. things are FAR more formal than the US...

I'm hoping we can leverage the $2500-$10,000 someone else may have paid to have this formally reviewed.Thanks for any information.
