Sounds like you're asking for a private lender to go into second position to convert equity into cash behind an existing loan on these properties. 

Meaning you can add another unit to your existing structure and 2 more units on the new subdivided lot.

ALE solutions, united corporate housing and alacrity are large companies in the insurance relocation space, and it is useful to go to their site and let them know you exist.

Website shows up as not protected domain - and no longer in existence that should say enough 

This policy will provide additional coverage above what your existing policy covers.

None of these strategies are new, all existed when I purchased by first investment but none were as popular as they are today.

However, if you plan on living in your existing house and when you convert the basement you can rent out for an additional $1,500 then your cash on cash return of your $50,0000 would be 36% (18,000/50,000), which is a great ROI.

@Austin Williams yes you can do a 100% cash out refi on your existing home with a VA loan, but keep in mind that you would need to finance it as a primary residence, which resets the 1 year clock that you need to occupy the property.

If such tax law prodigies exist, I’d love to meet them.

Again, if your $250k is true, and includes all the electrical upgrades, new plumbing runs, potentially new foundation pour (since I assume the existing garage slab is not capable of supporting a new two story house), I am guessing since I don't know the market, but assume you will have a lot of equity by completing the project.
