Families with two teens (or tweens) can get one room and their kids don't have to share a bed.

Quote from @Erick Pena: A "good" rental property is one that covers all expenses (mortgage, taxes, insurance, maintenance, property management fees, and any other costs) and still leave a surplus (commonly referred to as cash flow).Calculate cash flow as: Cash Flow = Rental Income − Operating Expenses − DebtThere's much more to it, but that's the basic idea.

So basically in my mind this would not be a great financial move as we be accruing about 200k more in debt if we were to sell one house and take the cash from there and use it as a down payment.

At it's basic level:Assumption: Asking the bank to turn the loan over to you and going through the normal underwriting process, credit, income, DTI ratio etc SubTo: Taking over the loan without telling the bank, no underwriting, no credit check, no income verificationBoth have risks, but it's not my intent to be detailed in this post.

Basically gentrified an old neighborhood.

If a family with kids values D+ then the probably already have it, so providing smart TVs where they can log into their subscription is sufficient. 

We typically pay somewhere in the range of $3500 for a new, basic furnance, including install, if there are no other modifications to the system required.
