There's been many times when I've had to step outside to take calls so clients can't hear the kids playing ( or being noisy) in the background.

Insurance companies keep a national database on homes and individuals regarding their claims.

@Margaret Buoncora,  If these are sold individually then each one of them constitutes a separate 1031 exchange with it's own unique timelines and reinvestment criteria. 

If they insist on sending individual rent payments, we charge an administrative fee to cover the extra bookkeeping effort and bank charges.

If you want to be analyzing that many deals (even when narrowed down to 10 MSAs you'll be looking at a lot of deals), I would stress that broker relationships will play a major role in your success level, in terms of finding good deals.

@Terry Lao if bad management continues, it will keep hindering potential buyers’ options for financing, therefore, keeping the market value of those units down as they aren’t “marketable” Only options for a potential buyer are private mortgage and/or pay higher rate.I had this scenario myself where I owned individual condos in buildings governed by associations.

That's where a security deposit would come into play.

So is changing sectors from residential to commercial or passive fractionals - all depending on th individual facts of your case. 

I purchase a gemini (which is basically a duplex where each side is individually owned) at trustee sale. 

I made a ton of money doing those but you have to be in for the "long play".
