<prompt> Human: Hi PFers,Ive been a long time lurker but first time poster. Please excuse me if this post becomes long. I just want to provide sufficient information in order to get the best advice possible.Im 26F, going on 27 soon. I graduated from a top tiered university think Caltech, MIT, Stanford, etc with an engineering degree and Ive been working in my field since graduation. I currently manage a team of 4 engineers and make 80K base plus potential 6K bonus. Im currently extremely unhappy at my job and its taking a toll on my personal life. Ive looked for other jobs but Im starting to realize that I dont want to stay in engineering and want to use my engineering background in a more business-oriented position. Ive recently latched on to the idea of quitting my job and pursuing my MBA to fulfill my next career goals. My current financial situation is as followed:Income:80K yearly salary up to 6K bonus I brought home 3K in bonus last year2800month from rental property rent is under market because I like my tenants. This number can go as high as 3500Debt:8K car loan 1.75 interest 290month 7K student loans 4 interest 100month 280K mortgage 4 interest on rental property 1730month 330K mortgage 4.3 interest on main residence 1000month no CC debt Assets:2010 Toyota Prius, worth about 13K Rental property, worth about 445K Main residence, worth about 500K this is jointly owned by myself and my fiance Liquid cash: 20K I know this isnt a lot, but Ive sunk a lot of my cash into my two properties in the past 4 years 401K: 10K employer never matched, so I only started this in Nov 2014, stupid me If I go back to school, Id get rid of my car, pay off my student loans in fell swoop so I wont have to worry about making the 100month payment. My living expenses like food and minor spending can be subsidized by my fiance, my rental income would cover my main residence mortgage. Im looking to attend a top tiered MBA program that could cost upwards of 160K for two years. Most of these schools claim that their graduates recoop their investment within 3-4 years due to the large salary increases. Statistics show that 90-95 of grads from these top tiered programs find jobs within 3 months of graduation that pay well into the six figures. Ive been fairly active on a few MBA forums and have noticed that a decent amount of people advise people in my age group to start their MBA if theyre sure thats where they want to end up in their career because the longer you wait, the larger the opportunity cost will become since your salary will get higher with time. I can see their point but Im just extremely nervous to get into this amount of debt. Ive thought about doing a part time MBA so that I can keep my income but based on the amount of hours I work and travel for work, this would be extremely difficult. Not to mention the fact that my job is already taking a toll on my personal lifemental health, I dont know if I can handle both at the same time. Would this be a stupid move on my part to get into that much debt? At what point would this not be stupid? Any other feedbackadvice is welcomed. Im not looking to be judged for my choices thus far so please keep your advice to what I should do next instead of what I couldshould have done. Thank you!  <response>: MBA from non top-10 or 20 at most programs may not be worth the 2 year time and meager salary bump - assuming you will even find a job immediately.If you can get into top 10 programs, then just do it do not think about the money. This is about long term career growth, not just about salary.
