That may have a positive effect for you.

. - My wife and I are 33 living in SF with $250k in cash & $250k in other equities. - $6k/ month is our freedom number from a W2- Buy & Hold MFH is our plan (turnkey with PM in place)- This quad was built in 2024 and we're able to secure a 3.75% 10 year rateHow's this deal looking or would it make more sense to go another route?

This creates a negative initial position.

But if your goal is to cashflow positive from the Day 1, you may find it very challenging due to current day interest rates, high cost of construction and the fact you won't have the efficiencies of a seasoned developer building at scale.

You can also do a live in flip where you use the equity to sell and reinvest down the road.

I was in a similar position with my SDIRA and decided on working with PPR.  

I mean I highly doubt( but sure there will be other who say otherwise just because) you will find a very good investment property listed on MLS or other publically available service.On a side note if I did have aprroximatley 400k equity in two of my homes could I use any of that to invest in another property?

The triplex is occupied and currently bringing in positive cash flow.

Others have gone into great length and I can say that I agree with the positive comments, especially from an OG Bigger Pockets great, @Jay Hinrichs.

Some have more than $1 million in equity, while others have less.4.
