I sold a Cabin in Packwood to an Airbnb investor client a couple months ago, and their project is turning out great. 

Emphasize your strong rental history and present business financials to showcase profitability trends and future projections, increasing your chances of securing the necessary funding.

The goal of this format is to provide an informal but regular space for conversation, peer-to-peer conversations and sharing of resources and best practices.

Seeing it as a great potential future home, I decided to make an offer.The offer was accepted, and I purchased the house with the intention of staying at my parents' place while renting out the home until I'm ready to buy a duplex, moving closer to my goal.

Even if the FHA program doesn't work out, they have other programs/products that'll be right for you and your goals. 

Albeit, all negotiations have similar qualities - both parties want the best deal, and if both go into the negotiation with an open mind and the same goal - to close the deal - the odds are good that the deal will be made. 

My goal is to get on with one of the big Brokerages that sells trophy ranch's and get back into land sales whence I started..

We send our contractor over to quote the project and he reports issues of damage.  

With this in mind, I think I share the same goal as you of having a solar panel on one of my properties - be it on my personal residence or an investment property. 

Likewise, calling to buy someone's property still has the ultimate goal of arranging to provide a service to consumers.
