The best way to do anything as a career is to have rare and valuable skills.

For example, foreclosure law requires a very specific skill set and knowledge base. 

I am very interested in combining my skills of construction and reselling to start flipping houses and BRRRRing.

People skills comes into play here.

Any other skills worth while?

Develop the skills to confidently analyze and invest in multifamily real estate. 

I’m using my money to improve my skills as a real estate investor and improving my business.

HELOC’s are a wonderful tool and I use 4 of them regularly, but like Ryan said you’d need to be confident in your rehabbing skills and process or you could become homeless if things go badly.  

Whether they can (especially the non-profits) helps sort them out.Maybe KY is different from OR, but congratulations whether skill or luck you snagged some very marketable properties.

@Katie Noe really showed out on this one displaying her impeccable design skills.
