Your warranty deed is only as good as the entity issuing it. Tracking down your seller years later to claim damages for not providing a clear title to a free timeshare would be a fruitless endeavour. Costly legal process for limited return. The best insurance if worried about title, is either a certificate of clear title from a reputable law firm or title insurance.
If HOA or marriott/wyndam/hyatt have issues with your title, agree with them, and walk away. No MF payable if you do not own it.
All said, a warranty deed is better than a quit claim deed, but it is of limited value unless issued by someone with deep pockets who will still be around if you have a problem.
That is why the banks need a certificate of clear title from a law firm or title insurance before they will issue $$ on a mortgage.
