Social Security, Child Support, and most disability payments cannot be garnished.

IRS liens, liens from municipalities, HOA liens, judgement liens from child support or alimony might not be attached in a way that's obvious and can appear after closing...

One downside from the new tax reform is that we lose the personal exemption at the federal level.However, the child tax credit increases and it is harder for it to phase out.Also since it appears that you have a small business where you work from home - you may be eligible for a home office deduction.

*One side is already rented with a longterm tenant (mom&child) and I do not see a problem with finding someone for the other side as rentals in this middle price range are highly sought after. 

I think it's time the investment community and lending institutions stopped treating Airbnb as the ugly step-child of rentals.

Child died in the property...

Perfect for a single parent with one child, don't know about 2 adult non-related co-workers on a corporate rental. 4 feet is not very high; see for yourself with a tape measure.

Then I also met some investors and there are plenty of YouTube videos talking about how the coming correction will make 2008 a child's play (I'd call them Doomsday guys, won't you?).

We plan to pay this property off in 10 years and at that time use the cash flow to invest in our child's education.  

This way you will know if the seller has IRS liens, liens on the property or child support due or any other items that cause the title to the property to not be CLEAR.But yes, it is legal and this is a great way to find foreclosures before they become foreclosures.
