In Philly taxes are collected/withheld/remitted automatically.

If I find the buyer but the contract is about to expire, I submit a request for extension (for a fee), that gives me an additional 15 days.

We even discussed that if he doesn't have a chance to submit the taxes on time and ends up submitting an extension (he was supposed to be moving offices), he will have to run the numbers, and if numbers show we owed anything, we would send a check  to IRS before April 18, 2016, and then IRS would reimburse us (if there's balance left) once he gets a chance to complete the taxes and submit.

It is an REO property and bank is going to ask for an extension for closing due to pending lien issues with the city.

Agreed, waste of time if it's not collectible.  

@Steve Vaughan  unfortunately the seller does not have the right to collect the rent they don't own it.NOw if they would have done what I always would have done when I was doing these as a seller I would have done a wrap.. in CA its called a All inclusive trust deed.. .. the buy buying it still buys it.. but they owe ME the payment like a seller carry.. and I make the payment on my loan thereby knowing instantly if they are defaulting... when you default to  a lender it usually takes a bit to find out ... and the damage to your credit is done.. .also with the AIDT you have the Assignment of rents clause that lets you go after the rents...

Connecting the original lease to the addendum extension. 

Katherine Earle You and your husband know what's best for your collective success.

It has four 2 bedroom 1 bath units and each unit collects $525 per month on rent.

This may be a question for the towing company, but someone might know - does she get charged immediately when the truck is called or pulls up, or must the vehicle be physically towed.Do have to make an addendum to the lease and have her sign in it in order to collect the towing fee?
