Guess it depends on what your seeing. But the market here stinks. Everything is expensive for what you get. Most of the cheaper duplexes are in rougher areas if they are cheaper. Once in awhile you will see a semi newer one with in the last 30 yrs but they are usually really expensive. Some of it I guess depends on how your financing goes also. Most places want 20% down and only do 20yr Amortization. So your payments are higher. I guess it depends on how much a month you want to make. Prices here have skyrocketed in the last 3 years a lot.
For an example a few years back I looked at a duplex that was maybe 90K. I thought wow, that's a low price. Ok so you do 20% down at 5% gives you a $475 P&I, $68 for insurance, $150 for taxes gives you $693. Add in 10% property manager, 5% for CAP Ex, there is another $100. Then you have vacancy and the cost of the PM to rerent the unit. So in that example it was bringing in $1000 a month for both sides. With out figuring in any extras you were at just $200 profit for an old run down place. I think rents are more now but in those cheaper older areas the rents are low. The tenants you get are not very good either. I think tenant turn over is higher because of the type of tenants you get also. I have never dealt with PM as I do it myself but I have heard complaints about a lot of them. A&A is one I would not give a chance just because I called them 3 times and emailed in regards to one of their clients selling some homes and NEVER got a call back. I do know 3 places off the top of my head that are smaller PM and I would check into.
Rents in this area are all over the board also. If you want to private message me some streets or address I would let me know what I thought about the area.
