My question involves landlord-tenant law in the State of: Michigan
Earlier This Month, my girlfriend and I signed a lease agreement on a 2 bedroom home. Literally days after signing this lease, her place of employment offered her an apartment on-site for a [very] reduced rate.
Quick Side Question: As I was looking at the lease we signed at the end of May, the landlord put at the top that the lease was made June 20th, 2014, which is actually our move-in date, and then lists June 20th, 2014 again for the move in date. This means that our lease was technically signed in the future? Does this hold any bearing legally?
MAIN Question:
Literally the same night after we returned home from signing our lease, the landlord informed us:
"after you guys left tonight I went across the street to talk to my old friends/neighbors. They had told me previously and I couldn’t remember if I had mentioned to you guys about the road construction that will be happening (I remember mentioning it to some people that came to look at the house, but couldn’t remember who). I am sure that you saw all of the flags and such in the yards down the entire street. When I talked to the neighbors before when I first showed you the house, nobody knew what the exact plan was – namely if they were going to do sidewalks or not. I found out tonight that they are going to do sidewalks on both sides and will be widening the road. There is only 1 house on the street that is happy about this as everyone will be losing basically half of their front yard. There are stakes in the yards with pink flags on them – that is where the sidewalk will go to. Basically, my house will be losing the flower bed in the front yard and I believe that there will no longer be room to park a car on the stones to the side of the driveway. Anyway, I didn’t realize that it was going to be such a big project. I thought that they were just going to be resurfacing the road and I feel a little badly that it wasn’t disclosed before you signed the lease – but please know that I didn’t know. They have told the people on the street that they will start in “July or August” and will be completed “by November. I am glad that the house has central air so you can close the windows as I’m sure there will be a lot of dust."
Now that we are reviewing our lease, we noticed the following clause:
#20 EMINENT DOMAIN: If the whole or any part of the lease premises shall be condemned or taken by an government authority for any purpose, the term of this lease shall cease on the part so taken from the day of possession of that part shall be taken, and the rent shall be paid up to that day. If only part of this lease is so taken, Tenant may continue in the possession of the same under the terms herein provided, except that the rent shall be reduced in proportion to the amount of the premises taken for such public purpose; provided, however, that both the Landlord and Tenant shall have the right to cancel this lease and declare same null and void by delivery of five (5) days written notice to the other; such cancellation to be effective as of the day of the possession of that part of the leased premises shall be taken with rent being paid up to that day.
Given this information, since she has stated we will lose half of our, likely this month or next, and given the clause above, do we have the right to cancel our lease, and if so, how should we go about it? According to the county website, her frontage is 66', but according to her, there is no doubt that she will be losing a majority of her front yard.
Thanks in advance for any advice.
