My dad considered a six month to one year vacancy between tenants normal.

I estimate we should be able to cash flow ~$400 per month after 10% for Cap Ex, vacancies etc set aside. 

Most of my clients run their SFRs at a 25%-30% (excluding vacancy/credit loss) operating expense margin and most of the banks I deal with on their DSCR loans underwrite using 35%.

Have a robust cash reserve to handle unexpected vacancies, repairs, or market shifts.Good luck, and I’m excited to hear how your journey progresses!

Start with simple repairs, plan for vacancies, and ensure professional inspections. 

However, after running the numbers accounting for insurance, PMI, taxes, vacancy, capX, property manager, etc. the property is estimated -1.85% cash on cash return (-$600/mo) once I fully rent the property.

Property Details- Size: 64,000 SF Class A mixed-use building - Commercial Space: 25,000 SF - Residential Space: 39,000 SF (32 duplex apartments, 2BD/2BA) - Parking: 165 spaces Vacancy and Rental Status35% of the prime commercial space (about 10,000 SF) was vacant and not marketed for rent online. 13 of the 32 duplex apartments were rented at 35% discount to comps What made you interested in investing in this type of deal?

Anyway, I would say vacancies do take 30 days to 45 days to fill.

Make sure you've got cash reserves for closing costs (around 2-5% of the purchase price, repairs and maintenance (aim for 1-2% of property value annually), vacancy periods (budget for 3-5 months of expenses), property management (if you're not self-managing), emergency funds for unexpected repairs.When choosing markets, look for those with stable job markets, growing population, and strong rental demand.
