Using the equity I built up in that property I got a HELOC and started investing remotely out of state.

Step 1: Ensure you can get financing (is it a cash purchase or will you need a loan). 

Key Factors for a Good Seller-Financed DealCash Flow: Rental income should exceed monthly payments (PITI) by at least 1.25–1.5x.Purchase Price: Compare to ARV and market value for fair pricing and equity potential.Interest Rate: Aim for competitive rates; higher rates must still allow positive cash flow.Amortization/Balloon Terms: Favor longer amortization and align balloon payments with your exit strategy.Down Payment: Lower upfront costs reduce risk but should meet the seller's expectations.Flexibility: Seek no prepayment penalties and fair late-payment clauses.Property Condition: Ensure the property’s condition matches terms through inspections.Seller Motivation: Assess the seller’s willingness to negotiate favorable terms.Exit Strategy: Have a clear plan for refinancing or payoff at term end.Portfolio Fit: Ensure the deal aligns with your financial goals and risk tolerance.Vetting multiple deals and consulting professionals is crucial to making sound decisions.

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?

Second home loan , conventional How did you add value to the deal?

If you are doing a live-in flip why not use that equity for a down payment with a refi or HELOC?

A turn-key provider would be a company that can handle everything from sending you deals that fit what you're looking for, assist in getting you pre-approved for a loan, rehab (if needed), management, and maintenance. 

The terms for a 2nd position loan on a rental is 6%, 25 year term,  and 2 points origination fee.  

This money gets added onto the back of the loan kind of like a VA funding fee does.
