Additionally, I will ask them to pay $75 per horse for pet rent, so it will increase the monthly rent by $150.Please let me know if this sounds okay, and if there are any other steps we need to take for tenants with horses.

Also a particular pet peeve pain point for me is designers. 

Sorry to hear that it's been a dog for you and your partners.

@Eddie Smith we've found the two biggest tenant complaints:1) Maintenance expectations not met (taking too long)2) Expectations of communication not metThere are many more complaints, but majority are tenant-caused that they want a free pass on: waiver of Late Fees, Payment Plans to avoid eviction, being allowed to get a pet or otherwise violate their lease with no repercussions.

Never heard of them before....but your typical real estate "mentoring" guru will invite you to a free 2-3 hour session, and convince you to come to all day on Saturday or 3 day weekend course for $299-$399, when you are at that course, they'll convince you to be a Big Dog player for full on mentoring at $15,000-$50,000.   

You rarely get phone calls from your tenants and they are business owners vs. folks with kids, pets, showers and toilets. 

On or before that date, they are required to pay the rest of the move in amounts (i.e. remaining sec deposit, first months rent, pet fee, etc) and sign the lease. 

If one of your tenants gets bit by a dog, falls off a ladder, etc. and they have a bunch of medical bills they can't afford, they almost have no choice but to sue whoever they can to get the money. 

Consider all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

Could you walk dogs and or babysit/housesit for your neighbors?
