Should I strictly just use zillow/real estate postings, or is there a better method that you would recommend?

What followed was a year of legal maneuvering, claims, counter claims, depositions, etc.

If it is a flip I'd look at recent flip comps and see what their rehab was like to get an idea of what the market is requiring to get to the desired price point.I would follow the same process for a long term buy and hold.Mike

This avoids the issues you get when taking on tenants that were not properly screened by the old landlord.Your only option now is to walk away or push current owner to evict or move to cash for keys. it may be to late to request the unit be delivered vacant, but if not that's what I would suggest doing. if you follow through with the purchase, keep this tenant on the shortest leash possible and start saving up for the (very likely) eviction cost.

I look forward to following each of you in your life.
