Besides, we have a child who is very allergic to pollen and has breathing problems so mold in the house would make him sick.

People new to the "terms business" when you are talking to sellers and buyers you are basically being "parent child"; we are the parent of the child. 

Since then I got married, had a child with another one on he way any day now. 

If however, you child was on the other skyscraper and the building was burning you would run across and save them for no money at all.

I found a child support lien on him which I believe can be placed on non exempt property.  

I have an all consuming day job and a young child.

The tuition runs anywhere from 8-15K depending on what grade your child is in.

We both work full time and have a newborn-- we don't want the tenants to KNOW that we're the owners ;-) I was hoping that the property management company could shoulder the maintence needs for the units and that the "50% rule" would cover the costs to pay their maintence workers etc.

There should be a clause in your lease saying that only the people signing the lease and children identified by name are authorized to live there and any body else "must have the express written permission from the owner".Obvious exceptions would be birth of new child or adoption/foster care.

Apparently when you pass an annual income of $125K/year certain you no longer get certain deductions like the Child education credit, interest deduction from students loans, and most surprising we cannot deduct anything from the expenses of our rental property.
