This is the least attractive option to me, but my girlfriend likes the idea of having a little bit more privacy and our own space. 

Mortgage interest deduction on your personal taxes is only limited by the $1 million threshold. 

To be a true second home, it usually will need to be more than 50 miles from your primary home and either near a tourist attraction, lake, near family, etc.

I would also let them know that the spilled pet food is a major attractant and likely the reason for the mice in the first place.

it is as you described below, since I am bringing a million it is worth it for them to bring me in next to them.  

It is fully paid off and worth around $1 million today.

This may be attractive as the lake & mini grocery store is near by and we have clean fresh air. 

Theres roughly 3 million licensed agents in the country. 1 out of every 100 people have a license. 87% of them wont have a license in 3 years though and will be replaced by new people.90% of all transactions pool in the top 5% of agents. 85% pool in the top 1% of agents. 

Currently we have 7 agents.We offer high tech lead generating website, software for electronic signatures , no monthly fees and give out leads to agents ( some times - since they are independent) and give a 75% commission split with the opportunity to get 100% cap.Any suggestions on how to grow our brokerage, attract the right agents and still be competitive?

This property is close to the Train station and an attractive opportunity.
