In this case my Father in law would be with us as a co-owner can he alone satisfy occupancy or say we were partnering with another investor could the partner fulfill ocupancy?

My intentions with this market is to use it to fulfill social responsibilities and to build a good reputation for my business (simply because I understand the market.)

I guess the worse thing for you would be if they fulfill their lease obligation and then at move out you recognize the place is trashed. 

The husband and wife are still responsible to fulfill the terms of the lease whether he lives there or not. 

Why would you want to take a 10% penalty to fulfill your retirement dream that is still 15 years away?

(Question: Do you maintain a continuing relationship and financial plan to increase potential of contract fulfillment?)

Granted, some people do it, but what I've found is a lot of these young retirees basically end up doing the same thing non-retirees do: they volunteer a lot of time (i.e. work for free), or start a business, or do something else to fill in the time-gap.I get it: FIRE is a popular concept right now, but aside from it being the latest buzz-phrase....what does it have to offer you that a rewarding, fulfilling career and/or starting your own biz wouldn't offer?

I would need to replace my fulfilling career as well.

I'm trying to do as much due diligence before I enter a contract and not fulfill my intentions for the property!

In my experience, not every buyer’s agent fulfills his/her responsibilities.
