In this case a true 2/1 would probably be better, but would the French doors make that less enticing as a rental, as I expect it would likely be rented to a couple, or a very small family who wouldn't need as much privacy.Thoughts?

This is not a very enticing purchase.

Any ideas on how to structure this deal in a way that it is enticing to the seller and a great option for myself/additional investors?

If you bring the deal, that’s usually pretty enticing so long as you’re willing to work hard.  

However I've been thinking about financing, and the very cheap and long term fannie/freddie loans are enticing.

What would make the deal enticing to you?

You could also entice someone with a partial sales credit with a potion of their lease payment going towards the purchase price. 

Our first plan was to get into the storage unit business, but I think we've found the Mobile home (or RV park) business more enticing.

You could reach out to hard money lenders via this site but you the terms will not be as enticing as a traditional lender especially not having any experience as an owner or manager but if you think you can qualify to refinance within a year or so due to increase in income/ credit it may be the better option to actually purchase instead of rent but I would still exhaust your traditional financing options including FHA if needed to get started with your first investment property.

In addition, new commercial projects have been going up right across the street, which might help to entice investors.
