If it were me I'd probably talk to the child in law and just keep it brief.

In which case its doubtful they will pay significantly more to invest in their child future.The conclusion that I draw is that when buying 2/1's, the school district should not be a big consideration.

Even at -5%, it would take over a year.Job openings are at all time highs; so, wage growth should continue, particularly for the bottom 50% of households.Spending estimates by all income levels, but most significantly lower incomes, are at record levels and inflecting higher still.Average tax refunds are higher (due to child tax credit).The data shows that the biggest segment of society is doing better than ever...that's what causes inflation! 

Broadly speaking, according to federal law, you must allow at least two people per bedroom.So with that in mind, it does sound like your tenant is in compliance with this - one child shares a bedroom with her, and the other two get their own bedroom.I would bring this to the attention of your HOA.  

I have a child in grade school and the activities are VERY time consuming. 

Only one piece of advice from me: between your killer job and your killer real estate investment skills, you have built yourself the ability to spend time with the child(ren) you wish to raise.

I currently own a house with my wife with a child on the way, so househacking isn't an option.Does my plan so far seem adequate?

Plus, what kind of message are you sending to your child??

I recently lost summer  lived with my youngest two year olds father and some apartments on 81st and Yale in Tulsa  they're kind of upper class but not they have rats out by the dumpsters literally the rats will come u...

Fair market value is still fair and they know it.Do not wait six months because by then you will know that Jane cares for her sick mom and is having car trouble, Suzy's boyfriend is not paying child support and etc..........and it will be harder to raise then.Just bite the bullet.and if you raise all of the rents to market value then you do not have to worry about chopping up the water by percentages.
