That isn't including any potential rental income or salary increases; it's just what my current circumstances are.So, while part of me wants to jump at the chance to get a multifamily house right now since I'll need a place to live in just 3 months anyway due to my lease ending, the other part of me looks at how much better of a financial situation I will be in this fall and thinks I should just wait.I totally agree though, if we get more good economic reports then the interest rates will increase, potentially negating any benefit I'd get in waiting until this fall.My credit score is 630 now, and I can't imagine that paying off all of my credit card debt would catapult me into a 700+ credit score by this October for a considerably better interest rate.However, right now, I'm only eligible for amongst the worst interest rates due to my poor credit score.Sorry, this was super long, but I at least listed my main concerns and goals.Regardless, I need a place to live in a few months though.

I look for those extenuating circumstances to do anything that is out of my formula. 

@Jessica Zhang You do take a mortgage, and depending on the circumstance (tenant in property), they will basically do a full doc loan but you dont have to supply a down payment for the loan. 

It can be both too high and too low, depending on the house condition, improvements made (or neglected) by the owners, the owners protesting these assessments, developments in the area etc.When you buy the house, your local taxes will be calculated based on this assessed value - until it is reassessed by the government (usually annually) or you protest their assessment (rules on protests very greatly.)

Might not be impossible, but terms may be much less favorable depending on the circumstances.

If you are selling for health, work, unforeseen circumstances, you might qualify. 

I realize it is a complicated topic and each individual circumstance is unique and probably requires professional advice. 

I would fully expect service members to be evicted when in violation of their lease- as all would, under normal circumstances.

Or perhaps another investor had plans to rehab it but circumstances changed and he needs to get out fast.

BRRRR is a viable strategy for many, but it depends on the investor's individual circumstances.
