The other thing to consider is the condition, you will want to do a home inspection to look for hidden defects on the property that could be expensive to fix. If a property is abandon, or a bank owns it the sellers disclosure will not yield much information.
Get in touch with a good real estate agent who can watch out for your best interest.
Your question depends on if that particular home goes up for sale and how it is sold. If it is sold as-is, then you may inherit any problems, taxes, water bills and liens that are associated with the property. When you purchase homes at Tax Sales, you are purchasing them without Warranty Titles almost all of the time, so you better do your homework. I just recently talked to a guy who purchase a condo at the tax sale for $15,000.00 and the property ended up having over $20,000.00 in back taxes that he is now responsible for.
If you purchase a home through Freddie Mac, Fannie Mae, HUD or a Bank. You are more than likely to get a clean insurable title. BUT, that is NOT the case each and every time, so again, do your homework. So depending on where you buy an abandoned home, yes you may be liable for any unpaid taxes.
Let me know if you have any more questions.
