Should I finance or pay cash on a duplex

[Zac Boelkow]

I am buying a duplex. I am in contract presently. My question is should I pay cash or finance... Purchase price is $147,500. I am assuming interest rates are around 4% in todays market and if I finance I would put 20% down. The duplex is already rented with two long term tenants paying $1400.00 combined per month. I feel like paying cash returns a much greater cash return per month than obviously financing would. If I finance the property I can still net aprox $400 per month on a 30 year term. The math on a 15 year term will only net roughly $150 per month. Typically I pay everything off as I am not interested in working for the banks. I am completely debt free and the money to buy this duplex would be 75% of my liquid net worth. Real estate is my passive income as I work a 9-5 that produces me more than enough money to live on... Any help, tips, suggestions, and or advice will be appreciated.

@Zac Boelkow, Steve is right; this would have been a cleverer question before you did the deal. By the way, it's not you who'd be working for the banks once financed, it's your Tenants who do! You get to keep 80% of the cash you'd otherwise have "lost" - so you can buy four more deals!

Would you prefer to have one set of tenants giving you a return for one property worth $150k, or, with the same cash, have five sets of tenants paying off five properties, worth $750k? My 2c...
