I'd have a Home Inpsector and/or General Contractor go over the place and make a list (Scope Of Work) with a tight budget.

The last part they showed us a TED talk and we had to write on a paper what I want to do before dying...then we had to stick these words to the "commitment wall"...Lastely, they ask us if we d like a one on one strategy the next day during the lunch (yes we are hard worker who saccrifies even lunch for what we want).

Based on the local market, $15k for renovations seems light—have you had contractors confirm this budget? 

Be conservative on budget and time.

We budgeted $100k and that’s our goal but have extra just in case something pops up so this $120k is a high number.

@Joe BellevilleTo build a successful multifamily property portfolio in Grand Rapids, set criteria for property type, location, and budget, build a team, analyze deals using the 1% rule, leverage house hacking, leverage local knowledge, prepare for tenant management, network, and focus on long-term goals.

Furnished Finder is great for travel nurses and more budget conscious travelers.

Costs will always go over budget. 

Site cleaning may be the single most underfunded line item on construction budgets which often leads to dangerous work sites.

I'd also recommend joining a local Indianapolis based REIA asap. the REIA will provide a group of investors who could get you some contractor recommends if you decide to GC the prop yourself.You said it "needs a little work done" but budgeted $50k so those two things kind of contradict unless the home is a larger home...just curious, what's "a little work", if you haven't had an inspection yet and don't feel comfortable evaluating the costs on your own?
