Is there a way that'd allow me to have her owner finance this and pull out equity in a HELOC or cash-out refinance in 6 months after seasoning while continuing to make payments to my mother going forward?

Convert to cash either by selling or pulling $$ out.

I would recommend pulling list from sources like ListSource and myreipro are a good website for sourcing leads as well.

If you don't find much online, you may be pulling figures from Brunswick which is a different market.

Because I want to get into real estate investing in doubles, I kinda want to pull out my 401k, which I know will take a 10% hit for taking it out early, and I will have to pay taxes on the amount, but I think it would be better off being used to invest in real estate, it would be less risky in my eyes, not sure how other people feel about this.I want to get into real estate investing, I want to buy a double as soon as I can, but being a new business, taking advantage of all the tax right offs I can, looks like I am making less money than when I worked for the company I left.  

Once you find a property in distress, it's fairly straightforward to pull up a deed and find the names of the named owners, but where do you go from there?

Pull all necessary permits for the renovation project which include Plumbing, Gas, Framing, Insulation anddrywall.

I liked the shelving in the laundry area (most buyers would appreciate that).I personally would stain the fence (you have 2 different colors), pull all of the garbage cans/yard debris containers and take a new picture. 

Instead of doing a conventional loan, My plan is to pay cash for it, then do delayed financing to get my money back, 80% of LTV of hopefully at least $60k which would allow me to pull out $48k of my money.

Supervising subcontractors, meeting inspectors and pulling permits can be a full-time job.Funding a flip:Pro: Funding the right flip can be quite profitable.Con: Correctly evaluating the project and the flipper requires extensive knowledge about construction, permitting, zoning and real estate resale values.
