Intent is to live in the largest area of the house, rent an already existing basement apartment on short term rental, add a bathroom and kitchenette to two finished rooms in the garage and create a second short term rental, and then put a yurt in the back yard with sole access to another bathroom that'd be installed in the garage as another STR. 

Owners are less likely to move generally, and any sign of distress results in them getting a lot of mail, making it hard to stand out.As far as changing your message, it is less about keywords, and more about creating interest.

The other units can be rented out, creating cash flow for you.

If it is a rehab with no plans on paper, then the house is already there and once demo is completed, I would engage all the subs so that they can see "behind the walls" where and whenever necessary to avoid the change orders as much as possible.I typically create the SOW and give that to the subs to bid, they in turn calculate the materials needed and the labor costs and provide the bid from there.

The goal is to build my portfolio and create positive cash flow.

I'm more focused on creating passive income than a property that will appreciate in value.

A side note your rental type dictates your customer.

I own an older house that's in decent shape but needs some renovations including adding dormer to our attic (or just raise the entire roof possibly depending on expense) to facilitate a closet and more headroom creating an actual bedroom.
