I have one more key question: Since I'll be starting my first-year job upon arrival, banks might be hesitant to lend to me initially.

For example, if I do S/P top stocks, I could get around 11%. but if I did real estate and I have a 800 credit score - could I do real estate and make it work harder doing turn key Multifamily. 

This is the Key do YOU think it has value that's all that matters.. 

Proximity to Nashville is key—properties within 5-15 minutes of the city tend to attract more guests, but a nicer home 20-30 minutes away could provide more value in the long run.Make sure to research short-term rental rates in both areas to determine which offers the best return.

@Will Almand A cost segregation (cost seg) study can accelerate depreciation on your properties, reducing taxable income by reclassifying components (e.g., appliances, HVAC) into shorter-lived categories.

Are you looking for "value add" options or turn-key?

Hopefully, not an expensive tenant or Fair Housing lawsuit.100% of what @Travis Biziorek states is true, but he left out a key fact - he lived in the Detroit area when he started investing here, so was able to self-manage and meet everyone he had to hire face-to-face.

The underwriting would be the key and some luck as well. 

But there are a few ways to shake things up:Cash for Keys: Offer them money to move out.

Based on my limited knowledge of real estate investing, one key is to buy distressed properties, fix them up and either rent or sell.
