I am seeing a roommate who does not have pets.Cozy furnished 1 bedroom with living room and kitchen privileges, your own private bath and a shared refrigerator.

Highlight the area shopping, business etc, distance to schools .

I bought this property with a private interest free loan from a friend. the person i bought it from need cash fast so i offered them a low cash offer and they accepted.I had enough money saved up to rehab the house with my savings.

Speak with someone you know in leadership or on staff and express your interest casually.Frame It as a Solution: Highlight how purchasing the property could be mutually beneficial.

Send me your site in private and I will evaluate it so everyone can learn from this, if that is OK with you?

I am interested in utilizing space again for group meetings, workshops, and for clients who may still desire private space.

I have a private investor who will lend his own capital for ADU financing.

So a majority of the ownership groups would want to sell, plus since they are more sophisticated owners usually would sell through a broker to get max price and not sell privately.  

Highlight the property’s unique features (off-grid, sustainable) and the area’s growth potential to show long-term value.
