I'm interested in purchasing tax lien certificates in Texas. 

Certificate of insurance 

My vision is to buy & hold, maybe a few flips along the way and be financially independent by age 50 (i'm 28 now).I don't want to sign a bunch of mortgages and my real estate law professor said tax liens are a unique vehicle for that strategy, but I don't know how they work or if they're riskier than I think they are.Anyone have any insight on how they work in Ohio, or success/horror stories in tax lien certificates?  

Since it needs a lot of work, it is usually difficult to get major work done while Tenants are in there.Also, You probably would want to get a lead certificate to protect yourself in this state, and that might necessitate them moving out if you need any type of scraping and repainting-otherwise might be a big liability with lead particles flying everywhere.I would research these 2 issues to protect yourself.

He ran into some financial trouble recently, and now is saying since the property rental cert wasn't updated (in my market, even if you have a valid certification, you need to update it upon purchase) although I have the existing cert to 2017.

@Jonathan Perez Make sure to have the tenants and current owner/seller sign an estoppel certificate before closing.

@Ayse Yesilyurt to see what else might be needed at closing, contact your title company, they can provide a checklist such as operating agreement (if one exists), EIN, Good standing certificate, etc.

The house is currently being used as a multi-family but there is no Certificate of Occupancy (CO) on file with DOB (Department of Buildings).

It looks like I have to pass a few certifications and have an internship with 2000 hours under my belt before I can become a full blown appraiser, but the thing that is keeping me from pulling the trigger is that there is some kind of schooling that I would have to attend for 150 hours?
