A step into that direction included me getting involved on the internet.

Great to see you take that first and maybe most difficult step in real estate investment: reaching out on BiggerPockets.

But he did not notify me before or after, and I haven't received anything in certified mail, which is an important step in the lien being valid.

A step closer to passive management.

I personally wouldn't recommend it to start off with, unless you're really up  for the challenge and know its' going to be $$$$ to fix up.

Challenge yourself to get creative...

You can follow the same steps that appraisers use, by researching what similar homes are selling for in the neighborhood, which will give you a good idea.My valuation of a property is purely based on the income it can/will generate.

I need to consult with one for next steps after purchasing from the tax sale.Thanks!

You just took one of the most difficult steps in real estate investment; the first step.

Step 1 of course, find new insurance.No, the bank won't call your loan, But they will secure Force Placed insurance, which they have a right to do, and it will costs 2-4 times what you'll pay for your own policy, and will have worse coverage, and you will of course have to pay for it, or be foreclosed on.
