However, she is now having buyer's remorse and wants out of the deal (she realizes it is not right for her kids now).So, is there a way I can come in and secure the property as an investor with the same terms she has as an owner occupied purchaser.  

Cheers to you for beginning your quest to securing financial freedom through real estate

I would be happy to share with you what I have learned over the years in terms of securing money for your deals.Welcome again!

There are others who have recommended me on BiggerPockets -- just search Shari Peterson in the upper right hand of this web page.

How do I go upon securing a possible agreement before they list?

The area is zoned for a max 4/5 stories with 15 units total, 12 of which are market rate.Construction financing is secured as I have a relationship with a hard money lender who is interested in financing the project, but would need to assume the property next door to move forward with a construction loan.

In that case the second category applies (below).Again, these rules only apply to what the CFPB refers to as a residential mortgage loan where the note is secured by a dwelling or residential real property that includes a dwelling.Most people only carry back a note once in their lifetime, when they sell the big house, retire and move somewhere else.

They will need to figure out the security deposit themselves.I advocate not getting involved in tenant interactions.

The result is that whereas 5 years ago passive investors expected little more than an investment summary, investors now expect (and demand) a private placement memorandum, subscription agreement, attorneys opinion, tax opinion, and full compliance with the securities regulatory environment, even on smaller deals. 

An Assumption Warranty Deed with Vendor's Lien and Deed of Trust to Secure Assumption were both sent to the county.
