Timing is coming together at this moment with cash becoming liquid and taxes are settled.

I have always had 80-90% of my total net worth invested in real estate and the rest liquid as a cash reserve besides maxing out my IRA, SEP IRA or Solo 401k for tax purposes.

But what if I gained enough liquid capital to introduce myself to more and more flippers?

Closing was four months, but that is because it was a foreclosure and things tend to move more slowly (depending on what bank owns it and how much they care about liquidating that asset).

I reviewed some at Lumber liquidators and they seem durable. 

With a conservative estimation of $800/side it would have me cash flowing approx $600/month or $7,200/year making my COC, 16%.In order to fund this deal I would have to liquidate some of my stock portfolio.

Since rent wasn't paid, you're in default on your lease and can be taken to court for back rent and related fees.When an owner declares bankruptcy, the court has a decide how to pay the debts and which assets will be liquidated.

I used Terminix and paid for a two year contract, and in a year they weren't able to get rid of roaches (they still use spray from the 1920s).

You'll need to have a net worth equal to the loan amount and 10% of the loan amount as liquidity.

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