Next (or simultaneously) find out if and how much the mortgage on the probate unit is.

What are the scrutiny issues that some underwriter's face when doing a simultaneous close or a back to back close?

Shortly following closing I spent every penny I had on a reno while simultaneously making some other very poor business moves.

Again...I have searched for and will continue to search for a home in a non HOA neighborhood (within the guidelines of my and my families needs)...to date, I have not located one.So...I will continue to envision my desired outcome in my minds eye...as many of the spiritual self help books say to do...while simultaneously working towards a viable solution (with help I hope).

Simultaneously, I have also been purchasing real estate...

I could get simultaneous full-time jobs in both fields and not break $50k a year.

Can anyone recommend a good title and escrow in orange county that will facilitate assignments and simultaneous closes?

Having multiple properties to meet the aggregate replacement amount and doing the exchange with other investors simultaneously is not an issue.Is this correct?

do double or simultaneous closings? 

If you are trying to do a simultaneous (back-to-back) close, I would contact a good local RE attorney that is familiar with the process.
