Only problem I ever heard of was back in the day some condo associations didn’t have enough primary residence owners and the whole complex would be off limits. 

Hi BP,I have a question when you have over $500K in gain when selling your primary residence.

But - I do hear that we get to avoid 500K of Capital Gains taxes since it's been our primary residence for 4 years.

Since it was going to be our primary residence, our standards were probably slightly different than they would have been if it were just an investment property, but we found that most multi-family properties in the Houston area are being town down and replaced with townhomes.

Based on our research, more than 50% of its residents are renters which bodes well for a fix and hold property.

I have owned a SFH propert for approximately 9 years, primary residence for the first 5 and rented for the last 4. 

My wife and I reside in norton mass.

I've read all the articles I can about 1031 exchanges but nowhere could I find anything on foreigners (non-US persons, non-US citizens, non-US residents, etc.) using a 1031 exchange!

in the resi space.the resident is usually not very sophisticated and has lived for free for a long time.. they are use to ducking creditors so will kind of tell you what you want to hear.. 

I purchased a home last year and the insurance company (Allstate) contacted me a few months after closing stating they did a random drive by and my roof didn't meet their standards and I'd be dropped from the policy if a few minor issues weren't corrected.
