I make my living talking on the phone, which is my comfort level. 

In your opinion, what level accuracy do you expect when it comes to estimating repairs? 

Stay closer to fishtown if you want faster gentrification and better bet.

I would imagine that these folks have a high level of motivation. 

If you have enough other resources to cover any issues which may arise, then weigh that against what it would take to get the rents up to market level or higher.2.

As far as I know modulars have state level permit, I haven't heard any federal level, means that the mod co needs to get state approval for all states to do this.

I have had my tested as part of the building inspection and the levels are fine.I do understand I need to disclose those levels to prospective tenants; however, I also believe I have to register these results with the state. 

Today they let me know that their financing isn't going well and they need at least 7 more days and may be staying much longer if their financing for the new house falls apart.The problems with this is that this is a tenant I inherited and haven't raised the rent up to market levels (but I did raise it on them).  

Somehow you will want proof of that amount just in case the PA Dept of Revenue audits the transaction; going through a title company will help you to have proof, because the PA Dept of Revenue will use the tax assessed value multiplied by the leveling factor for that area to impute the property value amount upon which transfer taxes are expected.

There are multiple levels of certification depending on how much remediation you choose to do, each certification level comes with corresponding requirements for routine re-certifications.
