@Bill B.It will give rise to a new option for younger generation. 

I have known and worked with Matt for years.I have attended his training and hired him as a consultant.He is hands down the best at what he does.I have personally raised over $50 million for my hard money lending company.I am grateful for a lot of people who helping me with this success and Matt is at or near the top of that list.

(This option would would not carry any debt, all debt would be paid in cash)Or keep our current house, rent it out, and cash flow NET monthly about $1,500?

Here is a link that provides fantastic information on the turnkey investing option from BP. 

Narrowing down the options will probably come down to comps and city/neighborhood specifics; things like permits.Any good suggestions for finding out how long permits are taking in certain areas?

I am looking for a RE financor/investor to lend me the amounted fix money we agree to buy the property for, and in exchange I will pay the investor a 6.3% interest by distributing monthly passive income to them in a duration of 15 years.Using the deal that I currently am seeking for now, This Fourplex is listed for $459,900. i plan to negiociate down to AT MOST $409,900 (50K less than asking price).

I wasn't aware it was an option.

The cash flow is a bit sub par on this one and I anticipate some larger expenditures coming my way in a year or two so I'm contemplating this as an option.

Due to the creativity of the deal conventional funding is not an option.

The second son is married but has not lived in the home at any point during the last 20 years so this doesn't seem to present any options for savings.I thank everyone in advance for your thoughts.
