I am starting to believe that I need to learn the tax laws myself since I have lost so much money paying unnecessary taxes because my previous CPA's are not familiar with all laws or they just plug numbers into a software (without strategizing) and then I get hit with huge tax bills that could have been legally avoided. 

Property Managers can also save you time, stress and legal compliancy to maximize your investment.

A neighbor 2 doors down also cited had added a staircase between his first-floor apartment to the basement apartment legalized and with the crazy rents in the area, collected rents now legally for both.

But, if you have clear evidence that fraud was committed, you may have legal action against GP, but this is typically hard to prove, and likely going to be costly for you to pursue, and if the deal is already failing, there likely isn't much of anything left to collect anyways.

My suggestion is to partner with / hire the best local tax and legal professionals you can if you are going to invest abroad.

We used Anderson Business Advisors to set everything up properly and have not regretted the couple thousand we spent, as well as the monthly fee for them to keep up all our legal and give us unlimited access to attorneys.

Part of your prepaids and reserves should have been 2 months of tax and insurance escrow paid in at closing, in addition to collecting the annual insurance premium and expected taxes due for the year in which you closed.

Check your local laws to see if that is legal.

We're in Arizona if that makes any legal difference.

What type of contract can I legally use?
