I make around $110k+ per year, live off around $75K, have a mortgage ($1900/mo for rent, escrow, tax), around $40K in equity, and no other debt. 

I've been knocking on doors, there is one that seems like it's abandoned, however despite finding the owners name from tax records I cannot seem to get in contract with them to make an offer (despite trying x, y and z). 

I just started using it and so far the owner info matches up with the county tax info. 

I am looking to purchase real estate for both investment purpose as well as to offset as much tax liability as possible. 

Taxes/Insurance- depends a lot on where you are located.The homes themselves- POH or TOH? 

Please note than may liability personal or corporate of the original borrower remains after the title transfer.

But, you still own house and benefits are as follows.1. tax benefits2. principal payoff on your note.3.

and how do you know the ARV (after repair value) is?

After doing this due diligence, I would confirm with the city first, appreciate the help!

network network network. anywhere there is one in your area go and meet someone and follow up is key after that. there are many good apps to find local RE events
