The Housing Authority will review the household makeup (I.e family size) and income. 

You can take a look at their site and they have options through which you can filter equity %, household ages, last market sale date, etc.

For a 2000 sq ft house, how much do you usually spend on labor (design, furniture assembling and household items organized) to have everything set up and ready for guests to check in?

Such changes can be done with an addendum or by signing a new lease.We have a procedure for adding or removing a person from the rental agreement, as changes in household make-up are not uncommon.

EDIT - So you can get 5 rebates per household on the single form.

I agree with @Max Householder and @Kyle Eckert the rents have been increasing over the years... and you can find some cheap buildings but you will have to go in and spend money to update the properties.

Typical US usage is 80-100 gallons/day/person but our households where WSG is still included are well over that.Now I prefer the utilities to be in their name, so they can see and understand the cost better. 

I basically want to track our household personal finances, as well as a few rental units we own. 

My Canadian income level (household) and credit rating is good but not having US credit history, it is extremely difficult to get a better rate/LTV.If you are available for a chat/call, I’m happy to arrange and discuss.Thanks!

If we are made aware the minor will come of age relatively soon, I would add a condition to the addendum that "Johnny Jones" will need to sign a new addendum at that time, and become a "Joint and several" responsible party to the Rental Agreement since you always require all adults to be signatories.As a side note, when a household consists of multiple adults, we consider the combined total income to meet the "X times the rent" criteria; NOT that each person must meet that criteria.
