Take baby steps and don't measure where you are by what others have achieved. 

I'm all about those hardwood floors throughout, baby!

Without knowing the exact situation, there are alot of duel income professionals who like family houses for the space, their fur babies, etc. 

Getting a former paying tenant, holdover tenant from a seller, semi-quasi-related baby daddy's family of a decedent or other interloper and their stuff out...legally...is quite another.I've been sued when I should not have and not been sued when my people cut corners. 

All because of the in-law suite. 75% of the foot traffic was represented by younger baby boomers (50 - 55) who were willing to sell their home along with a parents to purchase this one.

What I'd do with your complainer is probably sit her down and tell her something like, "You know, considering they have a baby, you're really lucky the baby isn't crying all night long. 

And another young couple had a baby while in the building, until they bought a condo and moved out - and they just bathed the baby in the kitchen sink.

As a tenant, there is a waiting list for these, and my experience is that they're well-managed and cared for.These are tax properties, with several different funding types, so some apartments are rented at market and others at different levels/types of funding, and all will accept Section 8 vouchers.It's big business - lots of baby boomers out there looking for this type of housing. 

Way less tenant issues, in my experience as a senior now in 55+ housing.  55+ does allow a percentage of younger people, and there can be more issues there.And with all of the baby boomers looking for housing, I would also advise you to learn about subsidized senior housing. 

However it is always a concern that tenants understand that high volume uses like running hoses for the garden and the baby pool every day are not allowed.
