3) Mathematics?

Just a simple touch on mathematics that may end up changing the way you structure your capital in order to allow for more deals to get done.

Do the math a few ways to see what makes mathematical sense.  

Mathematically, it seems to make sense to just say $1,000/mo "take it or leave it", but I'm just trying to see if there's a strategy that allows me to have 0% vacancy by keeping 10-year+ tenants.I think that anybody facing a $300/mo rent increase psychologically would just say "I'm out of here," whereas a $100/mo rent increase, I'm pretty sure they can get on board with. 

The timelines for the rehabs just don't make sense how somethings are mathematically even possible.

If the deal makes sense (mathematically) then I should do it. 

Understand: these guys use it to compare different projects, although the IRR is not the perfect mathematical tool for this comparison.

I understand the mathematics of determining whether a property is a good deal but am looking to get advice from experienced investors on what to expect for your first rental property.  

I guess if replacement cost mathematically worked out to still be a good rental I would go that route, but I'm not aware of any place where that is true.

4 - Realizing that cash flow is a result of a mathematical formula where you subtract your expenses (Including the mortgage payments) from the rental income, does the quality of a school district automatically increase the rent, and thus the cash flow you make when you rent?
