... as I was saying, this allows the investor to take a much bigger deduction on taxes over the first 5 years.On top of that investors who build their own  or buy brand new buildings get a "bonus depreciation" of 50%(!)

I received  what looked like an ad for free sign up (which I did) My question is do these events cost?

You might have to sign up for the pro account to get unlimited free calculation reports here, but this practice is invaluable.

An added bonus is that the VA rates are super low, I was quoted at 3.75% for 30 years.

My wife's brother and his wife live in NE Heights area, so if the rental market is decent in that area, living near them would be a bonus!

Rent for home and land brings $9450/year plus a bonus rent for space in barn and perhaps a billboard.  

Appreciation and real estate sales would be a bonus!

I've known a few people who paid a small flat rate and gave bonuses based on getting units filled (which is the most time consuming part IMO, showing and screening tenants) and they also gave similar bonuses when a tenant stayed and renewed a lease. 

Then if you decide it's something you really want to pursue you could sign up for a licensing course at a local community college (usually $750-$1,000).

It will be a bonus if the current tenants stay under the conditions you stated.
