Going to look at first potential buy and hold deal. Do my numbers validate digging deeper?

[Joseph S.]

Came across a foreclosed SFH that has been converted into a 3 unit building. Two 2br/1ba apartments and a 1br/1ba apartment. The list price is ~$350k, estimating $60k in rehab costs. I'm estimating ARV to be ~$450k. An identical, moderately renovated property nearby is renting at $1550 for 2br and $1150 for 1br. I would be looking to buy at as close to $315k as possible, but I calculated using a purchase price of $330k. I'll be going to visit the property with my agent and a contractor this weekend to get more accurate numbers. So here's what I have so far from the BP calculator:

Vacancy (10%): $316

CapEx (5%): $198

Management (5%): 198

Taxes: $375

Maintenance (5%): 198

Insurance: $100

PITI: $1,567

Sewer and Water: Tenants pay

Trash: Tenants pay

Heat/Utilities: Tenants pay

HOA: N/A

Monthly Income:
$3,950

Monthly Expenses:

$2,952

Monthly Cashflow:
$999.92

Total Monthly Cashflow using 50% Rule:

$408.42

Cash on Cash ROI:
15.35%

Any tips for the first showing?
