We are going to pull $ out of this home in  NJ, and the current plan is to move to the area, keep the jersey house as a rental, maybe house hack a duplex or 1 yr. brrrr.

I will pull back.The property is in Walterboro, SC which is a growing area but still rural fronting I-95. 

In a cash out you will probably only be able to pull 70% out, maybe 75% if you are lucky.

Been talking about it for years, finally pulled the trigger.

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?
