In other words, if the tenant is "not available" and won't give permission for someone to go insdie their unit that is usually a yellow flag. not a deal breaker,...but it can certainly make a number of people "pause". 

No one raised a red flag.

These things are all red flags I know will be raised in the next step with the FHA inspection.Main concern really are these tenants, if I can’t move them out, I can’t:a) get full rent to make mortgage b) I can’t move in myself under the FHA 203K rulesc) obviously not address the major issues properly?

If the investment has professional administration, you will have access to the answers to those questions, but also much deeper vetting of the sponsor that will include personal background checks covering things like bankruptcy, judgements, litigation, criminal history, and other red flags related to a sponsor that you would want to avoid, plus other items that investors rarely consider like ensuring that the properties are actually titled correctly.

Red flags for me 2-3 year lease too....they seem like they might be on the edge already.

Title company escrowed 2x the anticipated amount needed, so the incentive to the seller to actually follow through is to get the balance of their money back (about $8k), but the contract also states that if the seller does not pursue the riparian grant for whatever reason, the title company can use the excess escrowed money to legally enforce them to do so.I feel okay about it, I think, as this seems fairly common in this part of NJ, but any other red flags here I might be missing?

Too many red flags.

To me that's a red flag.

But if there are other red flags, this may be the straw that breaks the camel's back.

This alone attributes to something in the range of +$16,000 replacement cost of a standard american single fam home.
