I have had a fantastic response doing this, and I highly recommend you ask your agent to do it.For an investment property, unless there is some significant personal reason (need to have an address in a school district, rental is for your adult children, etc), I wouldn't recommend a letter.

I have two children, and decided to buy our primary residence in Summerville.  

A lot of the people pitching how great it is to drive a 25 year old POS with 300k miles on it probably don't have small children that they put in it. 

Not the perfect solution, but the lesser of multiple evils solution.The second part of your solution, giving the children to homes that want them, is another issue.

High earner should generally invest 85% in the safe market and 15% of the aggressive market ( start-ups).  3) If you have rentals and are such a high earner, you can hire your children so that they don't have to pay taxes on some of your income ( limited to standard deduction) or pay them more than the standard deduction and they still pay fewer taxes.  4) You can time the disposition of the rental property right so that when you have very high income in a year, you can dispose the rental property and use all the suspended passive loss that you were not allowed to take because of your high earnings in the prior year ( this loss can be substantial)  5) if you plan it right, you can convert some of the personal purchases to rental expenses ( lawn mowers, Ipads, laptops  you get it)6) some of the vacation travel might be planned right to make it a business trip and get tax deductions.There are much more.. so get started :)  

I have raised six children.

This is largely due to the substantial investments made by major corporations like Intel, Honda, Nationwide Children's Hospital, and Wexner Medical Center in the area, generating a wealth of employment opportunities.

I would advise my children to seek out a trade. 

However, not all tenants will have children and schools aren't always a factor. 

I do not have the funds to furnish the whole unit, or I would have thought about doing mid-term since I am less than a mile from Nationwide Children's Hospital.
