For those with significant experience doing this, am I better served using my benefits to get an MBA or to use them to take a myriad of courses at the undergrad level that could also help me, e.g. a few accounting courses, maybe some basic trades courses, marketing, etc. 

Thinking along those lines, head my advice to stay active, the advice and perspectives of others will greatly enhance your level of expertise and before you know it, you will be answering other members questions.

Split level, basements, converted garages are all ways to create more income and separation.

They need to be cautioned upfront that upper level units have an expectation of them being respectful of those below them.

To really understand it you have to be incredibly familiar with how all lines of the balance sheet, profit and loss, and statement of cash flows interact, which most people simply don't, particularly at the level of specificity required for a huge firm like this. 

Obviously there are more items to consider when refinancing like interest rate, term of the new loan, long term strategy of existing property and new property, cost of refinance, etc... but the above is how I would think about refinancing at a high level.

Need to be more creative for that : )    They offer it in a level that cost 1,200/month. 

The benefits come in two different ways:- You will get to deduct the interest at the new activity level.

It doesn't pay tons, but is honest work and the pay is a little better than most other entry level manual labor, and I can work as much and whenever/wherever I want.Also, I don't work with just one app, but quite a few of them(Instacart, Doordash, Grubhub, Uber, Amazon Flex...) and my income is fairly inconsistent in each one of them, but at the end of the day, I usually get pretty much the same pay every month(4.5-5.5k).I decided that in the near future I would like to get a small multifamily and househack to get started in the RE investing world. 

@Timothy Burnes Don't do it. 10-20k in equity is not worth all those issues.Bed bugs are a significant defect that can take either $5000 and tenting the whole building for heat treatment, which requires vacating the tenants or getting them hotel rooms for a few nights, or a sustained program of prevention with bed risers, leg traps, sealed mattress bags, and the tenants need to keep it up for.. get ready for it.. 6 months, which is how long they can live without a meal.Sewage in the basement could be a big issue if you have a sewer backup problem.The sinking toilet sounds like it needs immediate attention, but at least that's a straightforward repair.The other issues are what I would consider "normal" as in, you could fix them but don't need to in order to make the place liveable.Based on the bed bugs alone I would avoid... if you are comfortable with this level of rehab you should be getting a way better deal.
