What are the things that most commonly slow people down in the process?

It's not as common with pipe that is sitting empty most of the time - like a straight up & down stack - as it is with pipe with tendency to have standing water, but either way the inside of the pipe loses its smoothness and has a tendency to "grab" more things.

2) what are some unique challenges that arise when using these strategies?

Hi @Diana K. it's unfortunately a very common problem for out-of-state investors in Detroit.

The tools commonly talked about on BP aren't enough to figure that out, so you'll have to get a bit more advanced.  

Super common.

Google Search for @Dave Foster and Tenants in Common.

It is not uncommon for borrowers to have property deeded as tenants in common, so lenders will be familiar with this arrangement.

This seems very incorrect to me as the property would be a capital asset with depreciation deductions taken over years, yet the agent insists that he is correct and that this is a common practice for RE pros.I trust the agent but just think he is ill-informed and/or missing further details regarding his proposal, though I am open to the possibility that I may be missing something as well.Can anyone shed any light to help bridge the gap here  ?
