Eviction proceedings Pennsylvania

[Matt Daley]

I have my first investment property. 2 Tenants (boyfriend/girlfriend) signed a 2 year lease with first, last and security. Moved in 6/30/17. Paid rent on time so far. I get a call stating they are breaking up, tenant 1 wants to stay (and he can afford it all by himself based on pension). Tenant 2 states she also wants to stay but can not afford the full rent and refuses to leave (hearing this from tenant 1). They can not co-exist in the house together. If tenant 2 does not leave, then tenant 1 will do so. Basically will then need to go through eviction which I am trying to avoid at all costs. Home is located in Montgomery County Pennsylvania, just outside of Philadelphia. 

Has anyone ever had 1 tenant forcefully removed from a property while another tenant stays and a new lease is created? Is there any legal rights a tenant has to remove a non-paying tenant who is also on the lease? My though is as long as rent is paid, neither tenant can be removed. Just curious if in anyone elses experence this is true in Montgomery County PA.

Also, looking for recommendation of an eviction attorney.

Thanks in advance!
