It's not really that complicated: Whole House: ADownstairs: BUpstairs: CA has B&C calendars syncedB has A calendar synced (not C)C has A calendar synced (not B)When a reservation is made on A it blocks the dates on both B and CWhen a reservation is made on B it blocks the dates on A which in turn block them on CWhen a reservation is made on C it blocks the dates on A which in turn block them on CIf you sync B's calendar to C and vice versa, a reservation on B would block C which is not what you'd want

For instance, if I think the house is worth $80k and the mortgage being foreclosed on was taken out 2 years ago for $100k I just stop my analysis there because there is no equity and the lender will buy it back for more than it's worth. 95% of the foreclosed properties in my area still fall into that category so I can quickly narrow down the list.From there I do a physical drive-by.

60-150k for ARV is a huge range for ARV.First thing I would do here is narrow the ARV down as much as you can before you spend time really digging into the seller financing piece.Next I would try to understand what the property needs for updates and what that's going to cost you.  

Figure out what makes a good property actually GOOD and narrow your search range down to those.  

You'll take a tax hit when you do that, but it's like pulling off the band-aid.

Her biggest downside is you really narrow your market pool by only being able to sell to 55+ buyers feel free to ask any questions you may have. 

I like that you are narrowing your list to ugly absentee houses.

I narrowed it down to my major strategy/criteria.

I've read many considerations once a location is determined, but getting that narrowed down seems to be the biggest obstacle at the moment.
