It's possible the landlord has a separate account to power common areas but not sure of the set up there.

Taking the $50,000 with 8% guaranteed return example, it is true that a preferred lender has the right to get 8% guaranteed return before anyone else (basically taking $50,000 to give a $54,000 lien), but we commonly do see a structure where they have a buyout option at a future date. 

It's not "common" but can happen.

From what I have read , I am gathering that Direct Mailing is one of the least commonly used (but can garner high responses if you work at it) methods in finding leads.

Is it common to put in a offer as soon as you find a property before you look at it.

@Jeff Bousquet  The HOA for a condo will only take care of the common areas not the inside of the unit. 

I agree with @Mark Durham I joined several groups and cultivated a group of about 35 or 40 buyers.

There are approximately 80 units in the building, and I pulled my data (HOA and sq footage) from MLS listings in the past few years and the unit's ownership percentage of common expenses from the master deed.

I own a 10 unit building which has 3 separate entrances/common areas with have mailboxes, stairwell, etc. 

For example, I have an alert for a local municipality "Richardson"...this is also a pretty common surname and anytime someone responds to and tags, say "Joe Richardson" - I get an alert that is not relevant to me.
