It looks really green

As @Joel Owens alluded to you'll need some very high returns so as not to eat into your nest egg.  

We ended up doing a subdivision and selling 15 acres to an adjoining farmer with NO building rights and then sold the other 10 acres with 1 building right.In another area they had in their zoning that you had to have 2 lots in order to build on 1 of them leaving the other lot vacant green space.  

If he has renters insurance that will cover the damage and he is willing to submit a claim fine, but otherwise either file an insurance claim with your insurance company or just eat the loss.

During a boom cycle 15 years ago they probably made double what they make now or more.They are not evil because they got into a business to make money, most are hard working, they come from green to experienced and lazy to very hard working.I usually drive the listing price down to 5% on my sales because I already fix my property up and I know I can sell they myself if I want to.Some realtors make huge amounts of money selling 20 houses $500K a year and making $300K from it.

I liked the idea of multiple tenants because a single vacancy doesn't result in you eating the whole mortgage.If I had it to do over, 20 years ago, I would have bought a duplex and lived in one side and rented out the other.

Also remember that you have 5ft setbacks on each side of the home which also eats away building space.

Though I have done a flip and purchased a rental house, I consider myself green as they come. 

David Greene thank you very much for replying me here.

I am as green as green can be with buy and hold properties.
