If they want to stay, they have to behave and get along with the others.

Our experience: well-screened people tend to have well-behaved pets, and vice-versa.

I'm wondering if you are including electricity in that figure, because that would seem about right for a household of 4-5 people.The property I'm looking at is a 2 bedroom, 1 bath, and I will be having the tenant pay for electricity. 

Matter a fact he missed understand what I was explaining to him about subject to and he understood as he would need to continue to pay the mortgage for an additional 6 months until I behave the property and sell it.

They may own (free and clear) a nice car, some jewelry or other items of adequate value (or preferably great value) to act as compensation for the lost rent.I'm not suggesting that you open a pawn shop service for wayward tenants, but in this one case, since you're seem to be having difficulty taking direct action against the children's welfare, you might want to barter for the missing cash component of the next three month's rent.Like others above, I however still confused about why you as the listing agent are burdened with this decision.  

In addition, review the schools around you since you will be having a family around soon.

And if they have a pet, meet it first to to make sure its well behaved and friendly - I don't want a mean dog peeing all over but it seems like if you can find a responsible pet owner, an extra $50 dollar a month pet fee along with a pet deposit would help expand my tenant option and cash flow!

Talking to real estate agents or landlords familar with the neighborhood should be have an idea of what buyers or tenants expect and are willing to pay for.Good luck!

Rentals are one area where the little guy can still compete with the mega corps and large apt complexes, often winning over some choice tenants with personal service, flexible terms, and small touches...Just a few ways, off the top of my head, that I think we can gain a competitive advantage over more rigidly run large complexes (though all markets vary, so these are based on my experiences)....) flexible terms (I offer a six month or one year lease; of course, most six month folks renew, but some like the flexibility; some large complexes are "one year or nothing" in my market..)) new mats (inside and out of the doors; bath, even runners or area rugs in high traffic area for vinyl plank flooring)...while they add some "wow factor" and look like gifts, there is self interest at work here, however, as the matting greatly reduces wear and tear on my flooring.) pets on approval ( I have some of the best behaved canine tenants imaginable, and their high quality tenant owners stay long term, are respectful, and pay well,yet are often shunned by many "no pets" larger places)) small (tax deductible) $20 gift card at holidays ..

If he could not meet the expectation, he should have behaved professionally and at least communicated that he would be unable to make the commitment.
