After those 7 days you can apply for a writ of possession and give to marshal.

Thanks everyone for your response, I spoke to an attorney regarding this matter and they say a Notice to Quit is mandatory before starting Judgement of possession and the eviction process.

If I were to buy the property, and take possession, what happens from there?

Filing a writ of possession? 

Growing pains aside, I look back fondly at that home as it laid foundation for the expertise I possess today. 

Their collective expertise begs the question: what insights might they possess that surpass my own?

Figure out your next moves, legally get back possession of your unit and get it ready to be rented again!

And, the only landlord/tenant issues that my clients have ever encountered has been with 'acquired tenants' (I personally will only acquire under vacant possession). 

The grace period just means you are losing time to get a resolution with the tenant or get possession of your unit back. 

For example, since we don't have possession of subject property, they wont consider the 75 from other 3 units to qualified, nor the projected income from our primary residence once we move to the 4plex.
