@Kristin MathernI would pay it given no keys were provided, it wasn’t specifically addressed/mentioned in your lease, you were provided the opportunity to address/fix yourself with a 25-30 dollar replacement from Lowe’s/Home Depot, and lastly, it was an existing situation that could have been avoided/prevented at move in.

You can look into the fix and flip route.

If you're willing and able, I do recommend the "house hacking" strategy which is just a fancy name for buying a rental property and living in one of the units, because you'll get very favorable financing - an owner-occupied fixed-rate 30-year mortgage.I'd also say, analyze that property as if you won't live there and it's a pure rental, and make sure the property is still cash flow positive if there's a tenant in your unit because then you'll know if it's actually a good investment.And when you analyze it, include payment of a property manager in your #s because if you don't, and doing so would make it go cash flow negative, then you've just bought yourself a job because you literally can't step away from managing it without losing money.

Your best bet is a Fix and Flip loan (HML).  

Then once it's acquired and/or fixed up you could shop around for long term financing if planning on holding the property rather than flipping it. 

some like to fix and flip some like to hold for cash flow, figure out which you like and take it from there  Monthly...so guess rentals.

Problem found by expert, but you chose to not fix the problem by expert but by tenant.  

30-year fixed DSCR Congratulations...
