Some house electrical/cement businesses/pool-spa stores or just coffee/bake stores.

The issue is not having enough bathrooms and I am wondering if there is a large enough rental pool for folks who don't mind sharing a bathroom. 

@Kaleb Adam Barlow Some call outs... this is in a 55+ community which means your rental pool is immediately smaller.

I don't mind working with a RE agent on this, when I said go it alone I was mostly just hoping to finance the purchase myself and not have to pool money with someone else to get a loan. 

Including water bill with rent may increase tenant pool and make your property more attractive.

I'm located in sunny Dallas TX and want to start investing!

I think they do that because they are inflating their assets so they can increase their loan pool.

As the current employers die out, your tenant pool’s jobs will vanish and so will their ability to pay the current rent.

Or, perhaps, you have developed a healthy pool of investors ready to commit to an opportunity.

If so, you open yourself up to a larger pool of candidates.
