You should know how you can contest your assessed value, especially if you are buying the property for below current assessment.You should understand if there are any tax abatements available today or in the future.There are real estate tax consultants in basically all major markets, or your real estate agent can likely help with some basic questions, as well.

All these providers balance speed with compliance, so it’s worth consulting with them to compare timelines, costs, and support for your specific needs.

If she tries that, you should consult an eviction attorney and do what you can to get her out. 

Don't trust your agent, trust me the unlicensed "real estate consultant" who is clearly full of crap instead... uh, what? 

I was able to get 27 lots ranging from 3-15 acres a piece.We have consulted with Soil Conservation and the County Planning Office.

I'm an IT Consulting guy by day & RE investor by night so getting into the details of all of the technology offerings, how they integrate, which capabilities overlap/don't, where integrated value sits, etc. exposes my nerdiness/love for this kind of stuff.

My husband still works, and he has a consulting business, so for now we are ok, not great but not yet dire, he works 100% remote so only if it makes financial sense moving OOS to fulfill next step to get to financial freedom- it is an option . current picture. 

Consult a tax pro to maximize these benefits!

Always keep personal and business accounts separate, document all transactions, and consult a CPA or attorney to ensure compliance and maintain liability protection.This post does not create a CPA-Client relationship.

If we put what her husband did to the side (I would recommend that your friend consult an attorney for that) and assuming "made the HELOC go away" means to pay it off, then most certainly this makes sense.
