I am also considering selling the property next spring so this would be the last lease and I don't to play nice. 

For investors who own or have owned wedding or event venues, what are the typical lease terms you've leveraged?

The underwriter of your loan may want to see your current property be leased and make sure that it covers your PITI, but that will depend on the guidelines of your lender.

I recommend dropping your price (not your standards) and renting it for a shorter term to get through the winter months, then look for a one-year lease again in the spring.If money is tight, you may consider selling.

I'll add to the lease I guess?

There is an Hoa that requires minimum 6 month leases but that was only restriction.

Have the tenant sign a Lease Amendment indicating that the tenant is responsible for the cost of installation of the charger, any maint and repairs, and also removal cost (if desired later by you or the HOA). 

Is there a way we can ask our tenant to resign a new lease without having to tell them that their current lease is void?

Here's a copy of the letter, here's a copy of the receipts for both reg mail and cert mail....here's a copy of our lease. 

They want $1000 for lease up.
