I'd hold if the situs is right. 

Buyer immediately files Memo of Agreement in the situs county.

The notices have the property address where you can then go into the county assessor' office and pull up that address and hopefully get a situs and mailing address that you can send letters to.

@Nick KnoblachOf course, you should always confirm with your own CPA who is familiar with your situation, but here's a few generalities:- CA taxes residents on worldwide income, so the CA resident will likely be taxed on the entirety of income that he/she receives on his/her CA resident tax return, including his/her share of rental income- CA will likely want to collect tax on all income earned in CA due to CA-sitused real property, so any non-residents in CA should likely be prepared to file a non-resident income tax return in CA to report his/her share of income earned from the CA real property-I'm not familiar with MN rules, but most states generally allow for a credit for taxes paid to another state. 

I think part of why it is so confusing as the law says one thing but Judges rule however they decide to.Our properties are held by Wyoming situs trusts and a WY LLC is the trustee I am manager of the LLC.  

And those are found of course by just looking at the non situs run on the county tax records.Also @Joel Owens  I don't see Joel driving around and looking to see if some 100 unit apartment he is brokering happens to be vacant...

Even using zip code will eliminate some records as the assessors tend to have a lot of parcel with incomplete, missing, or inaccurate property (situs) addresses.

You would typically need the APN to start your search and maybe the property situs address.

Does anyone have any feedback on Situs Real Estate operating out of Denver, Colorado?

I may have a filing obligation even where there is no income tax due.Each state is given pretty broad authority in establishing their jurisdiction (nexus is just the right/jurisdiction to deprive one of property essentially).So Ohio I know is complex because I had to prepare a couple.Basically for state income tax nexus is determined by situs of real property.
