However, for the seller to net the agreed price, the price has to go up in which case you can run into the issue of the property not appraising.I think the fundamental issue is this requires a more sophisticated buyer and seller (especially to have a graduated commission scheme which is common in commercial). 

Los Angeles may provide more stability and long-term growth potential owing to its stronger market fundamentals, even though Philadelphia can have better cash flow possibilities.

If I can't call and reach someone, that's a fundamental failure (don't give out your phone number if you're too busy to pick up the phone when someone calls).

Fundamentals are key for me. 

the claim that PM cannot share tenant's credit file / application is fundamentally incorrect because (caveat - not a lawyer so this is not a legal advice, was told this by a lawyer, but you still need to talk to your own lawyer)1. the business relationship is between the landlord and the tenant, not between the property manager and the tenant - property manager is given limited rights by the landlord, which include tenant screening on the landlord's behalf, collect rents, etc. and all such limited rights are fully revokable. 

Comp's only matter for opportunity cost and appraisal purposes but if doing first 3 fundamentals correctly it always appraises.
