When the building is fully rented allowing for a 10% vacancy the NOI will be $136,800.00 which will put the value around $1,700,000.00The refi I have in place at current rates will give me about 200K cash out and 50K cash flow a year.There's a ton more I could add in here but it's already a long post.

In a rental I manage, we did see about a 40% higher rent for a furnished unit, but may see some higher vacancy periods and tenants probably expect more included (utilities, internet, etc), but agree it's something to consider.

You’re $20k will be your future savings that you will need to have around in the bank for when your property needs repairs or there is a vacancy.

Taxes, Insurance, Vacancy, Repairs, CapExp add up to $615 (insurance may be a little high until i get it quoted).

I feel like if we buy a multiplex, it becomes too risky with a lot of maintenance and possible vacancies.

Is there a standard multiplier like say 20% of rent goes to vacancy and opex? 

Will owners be willing to pay higher Placement commissions/fees to get their vacancies more attention to fill them faster?

This assumes some holdback for capex/repairs/vacancy that will be lumpy and (hopefully) not occurring every month.On a $200,000 interest-only loan at 9% you'd be paying $1,500/month.

Wondering if these are c/c+/b class neighborhoods and if tenants will be long term tenant and what the vacancy is like in North Linden Ohio.

Normally when you hear cap rates this high the expenses are not calculated correctly or certain expenses are omitted (no vacancy loss, no management fee, light on repairs etc).
