None of the leases have provisions for annual operating expense (ie CAM or NNN) adjustments, and my insurance and tax expenditures are increasing.  

If you can figure out the liens adjust your price accordingly and also reduce your offer to offset needed improvements.

This is money in the bank each year and if a recession hits i have almost no impact in my portfolio as i will just keep the building until the values adjust to my target sales price ($150k in this example). 

You need to decide what is more important to you....Enforcing your type A personality that demands rent on the first regardless of crcumstances because you are the landlord and they are the lowly tenant that should is blessed to live in your property and should always bow down before you OR think like a logical business man that recognizes the value in a long term tenant with a history of paying, albeit it late but for a logical reason and offer to make necessary adjustements that will benefit all parties.  

I used to be a licensed agent years ago, and when we sell a property, I still put owner/agent on the sign or in the online ad just to stop all the real estate agent calls trying to list my property. 

It the green one and it is very heavy (12" blade) I try not to move it often once its on the stand at location but the saw is excellent.

A level of 4ft or longer, chalk line, lap clamp, joint flashing, hardie saw blade, and a good saw for professional cuts.  

I've tried different things here, and I'll continue to adjust.

Ken -I am not familiar with the community adjustments you mention.  

You need to get started and adjust as you become more experienced and see what works for you.
