If Y remains independent, any legal or financial issues it encounters won’t directly affect the parent LLC (X).

The couple times I have bought with these liens in place, it has been done correctly, but you should definitely make sure proper notice was given or the IRS lien technically remains in place.I disagree on duration of redemption period as you posted it; see link below for 26 U.

Closing and fixing a house def takes up more then the remaining 1/2 a job even as I do hire out as much to contractors. 

This is because the Schedule E is obtained independently, and few people would inflate their rental income in that form (and pay more taxes than they should).  

All of the activity of the property remains on your personal tax return. 

As far as I know whatever the rent is for that unit will remain the same and small increases of 1% or so a year are common.

Reason I say "NO" to any Heloc if its for a Down payment or over $150K is because Heloc rates will remain higher and the terms are always under 30 years versus a mortgage.

I would take 0 cash flow on an 8 of 10 appreciation for this century over a few hundred dollars cash flow per unit and appreciation for this century that is lower than the inflation rate.  

But rental income is our hedge against inflation - we get to increase it each year (just like inflation).
