-22 years old-$50,000 pre tax income from business this year-80k in savings-30k in investments-pre approved for $350,000 (had to use parents as co-signers because I started business 2 years ago and didn’t make much first year)Looking to get into first house by house hacking a 4 bed 2 bath renting out 3 rooms.

We’re fortunate to have an above-average income and live well below our means.This summer, we’ll be moving to Detroit (PCSing in August), and we’ve saved about $120,000 to invest in addition to having funds set aside for the home we’ll purchase in Detroit.The reason I’m posting is that I’m struggling to decide how to best allocate the $120k.

I would just make sure you're saving for reserves and expect that first year to be really about learning the house.
