Returning to work - Explaining the job gap.

I've been a stay at home dad for the last 8 years, but my family's needs have changed, and it's time to reenter the workforce. I'm wondering what people thoughts are on explaining the gap.

All the first two years were primarily SAHP stuff, I did have a lot on my plate; especially once my daughter started preschool. In addition all the inside homemaker things, I also did all of the outside house work. I managed multiple rental properties (doing most of the work myself), performed significant home remodel and expansions, as well as being a general contractor (and doing a lot of the work) to build a second house on our property.

I'm wondering how to put this on my resume? My initial thought was downplay the SAHP stuff, and really focus on the self employed property manager/general contractor aspect. I recently talked to friend that's still in the industry, and her boss recommended highlighting the SAHP part since that is accepted a lot more these days.

If it matters, I used to work in tech as a computer engineer/data scientist. I'm 47 years old, so I realistically may be aged out of getting back into that field without a personal connection. I applied for a job that had an identical title as my old job and received an immediate rejection, and the job was reposted two days later.
