There is an annual fee to get the house inspected.

I would insist on either higher than market rent, a non refundable option fee, or a higher than current market price for the purchase option.

There is actually quite a few differences between the loans with their structure and fees but for rental income here's what you need to know:FHA loans will require there to be 25% equity in the property you are leaving in order for them to use rental income. 

I don't have a team in place, the building I'm in is actually very helpful and allows me to use their maintenance service for a fee.

I understand we may need get a motion to sell from the judge. my first offer is to have the seller put the property in a land trust and assign the benificial interest to my LLC, and pay them a fee for this as well as take over the underlying loan, pay the arrears and get the loan reinstated.

There are many neighborhoods like my mom's here and I am looking to carve a niche with these what I call "Hidden Pockets".

Like others have said file an extension and pay an estimate of your taxes so you can eliminate or avoid a majority of late fees/interest.

They pay rent up until I have it rerented and pay a rerenting fee.2.

How about outside contract services, legal fees, permit fees etc?

Condos are rarely good investments anyway; the HOA fees eat most of the profits.
