I know which are good/ bad from a renter's perspective and would be interested to know which are friendly to investors.Also, the school's student body grows larger each year. 2 year lag between incoming class and when they move off campus.

I am interested in building more new rental units with alternative energy features that will produce rental income and residual income from energy systems.

Crashpads are great income producers, but if you are not crew you might run into issues getting people to replace the crew you already have.I currently am a partner in 3 in DTW (I retired a few years ago) with someone who still flies.  

Using the income they say the property produces, that is negative cash flow before taxes, insurance, and maintenance. 

He has substantially more monthly cash flow due to being a business owner and therefor is moving faster.My wife and I have decided to "GO FOR IT" and start with shopping for a property with a goal of 5 total, producing a retirement income of $5000 a month once paid for.  

Now you have two cash flowing properties that are producing you a good net profit even after paying your credit partner.

Sometimes simply googling or binging an address will produce some info.

When the time eventually comes, I would like to invest in an income-producing property myself!

They produce a news letter and offer training as well. 

That is, to use a different metaphor, if you're throwing whole kettles of spaghetti at the wall trying to make something stick, you may need to select a more effective strategy.I wouldn't judge "massive" by volume rather by how much research is done prior to making ANY offers - so you're making the right offers on the right properties.There's a parallel in direct marketing: an untargeted mailing typically produces less than a 1% response rate.
