Artem,
Good afternoon! Thanks for opening up the link. Assuming numbers are for year 2, when you rent it out.
1) Make sure all utilities are in the tenant's name, including sewer/water, trash, etc. In northern Indiana, you should be able to cash flow around $125 to 200/month on a property like this (SFH, 3 BR, 80k purchase + repairs, rent at 950). Take those expenses off of your balance sheet; don't include them in rent; you could be stuck paying late fees, penalties, and overages you don't have money for.
2) You can reduce vacancy to 5% if you're signing them to a standard 1 year lease. With SFH, you're likely to keep tenants for at least 2 years with proper vetting. 5% is the equivalent of 2 weeks per year, so is conservative for the area.
3) I would highly recommend using a good property manager after you move out. They will charge 8 to 10% based on property condition and the local market.
After you remove all the extra expenses from your balance sheet, this deal might be tenable. But for this area, shoot for at least $150/month cash flow. If you don't get that, you might consider waiting for another deal. Try using a site/app called DealCheck to run the numbers; it will provide you with good conservative results you can rely on.
Good luck with the search!
