I have a small, one bedroom apartment that was filled by a property management company with a household of 4 ( 2 adults 2 children ).  Being a one bedroom 900 sq ft space I thought a household of 4 was a stretch but who am I to question a professional management company.

Two months ago the renters allowed another 4 people to move in, taking the total household size from 4 to 8 (now 4 adults and 4 children).  I filed for an eviction and it was granted but now the renters are offering to pay an extra 50% over the originally agreed upon rent if I let them live like this.

I hate the fact that each member of the household has 100 sq ft of space, I hate the fact that there is no privacy and I feel like that is no way to raise children however this is what they want and they are willing to pay for it.

What are the repercussions for creating a separate lease and allowing so many people to share such a tiny space?

On the upside, the monthly income from the building is going to jump to 8.8% of the original purchase price which is an insane return on investment.  I know I will likely have a new set of headaches in 4 months but at least I postpone those headaches until the winter months have passed.

What do you think, should I take the high rent and let them live with just 100 sq ft per person, should I go through with the eviction or are there other legal ramifications that I should be concerned about?
