( I don't want to just make my money on the land-- I can do that myself by selling it) What joint venture terms/structures would work for something like this? 

Joint venture with me :) 

Hey everyone , my name is Frank and i'm looking for likeminded investors who wants to invest in multi-family in Ontario Canada or US , right now my investment portfolio is 5 condo apartment doing short term rental (airbnb ) , would like to do joint venture with other investors

After having your own experience, you'll know what to look out for in a Management company, and I can say this from experiencing first hand.I would connect with other investors that are from Arizona, you can sign a joint venture agreement with them, giving them either a percentage of your rental income or equity, and they will be your boots on the ground. 

If anyone is interested on a joint effort, please reach out.

Hey Everyone I have a specifically random question.What is the process to getting a Line of Credit to a Mobile Home Park that is in a Joint Venture?

One reason I am looking back to my country (USA).Regarding finances - annual cash income, jointly with spouse, 200-250k.

This can give you bigger tax deductions sooner, which might help balance out the tax you owe on your sale.Capital Gains Exclusion: Since you lived in the property as your primary residence for at least two of the five years before selling, you might already know about the $250,000 (single) or $500,000 (married filing jointly) exclusion on capital gains.

In that case, you can sell as the LLC and buy as yourself (or as you and your wife if you file a joint tax return). 

We file jointly.
