So, what I'm say is this; if you fail, and acquire a lot of debt, and if you use your home as collateral then you can lose your home.Get it? 

What I have found when speaking to attorneys on 1st position notes and getting a deficiency judgement is it can cost $1,000 - $3,000 to get the judgement, and unless they have other properties as collateral your chances of seeing that $ is slim to none and slim left town or you hope slim hits Powerball or megamillions.

I did a quick search, and found some people who said they had borrowed against their TSP for real estate investing purposes, but I was wondering if I could pool the hive mind for some more details on the process.When borrowing from the TSP do you arrange it through the TSP or is it a 3rd party lender with the TSP as collateral?

The bank will have to be included in any lawsuit you file but unless the land significantly affects their collateral, in my experience, they don't really care. 

If so, DO NOT loan your neighbor any money with him using the house as collateral. 

And, there are private lenders in the Raleigh market who would cross collateralize (taking a lien against one of your free and clear properties)....more expensive than a HELOC, though.

This can affect the feasibility of collateralizing your hard money loan, and the refi (you might need two, or three, loans instead of one, which not only increases the difficulty of getting the refi(s) through underwriting, but could mean 2-3 sets of origination and closing costs).

Non-collateralized lines of credit are high risk themselves, so generally we ask for borrowers to have 1:1 liquidity.

Credit, DTI, collateral, etc?

Once I sold the collateral at auction to take it over he continued to threaten and intimidate the tenants to pay him rent.
