Help Analyzing A Start

I am 25. I’ve made 90-100k for the past 3 years, but since the real estate market has been so hard to reach I’ve been pouring into retirement. Now I found a property I think makes sense at 109k in a rural area but a market that supports my plans. 

I only have 15k cash even if I pull out of my brokerage, (40k in retirement i don’t want to touch), I’ve toured the property in real life. With 15-20k in repairs it would rent safely for $1,100 or sell for 155k. I’ve brought in a partner to help with down payment and repair costs. Better to do that then let it pass by in my eyes. 

I guess I just need help pulling the trigger this week. Please ask questions, give advice, and help see if I have answers.
