If you want to hold rentals, you MUST go into those "working class neighborhoods", IMHO. I've yet to see any evidence anyone can make money with "nice" rentals. You can use the rent in those cases to cover the PITI payment, and maybe some of the expenses, but those are really speculative plays. You're hoping for appreciation. Very, very dangerous, IMHO, in most places right now.
You're talking about being all in on a property at about $275K. You need $3650 in monthly rent for that to be break even. On a $100K house, you only need about $1350 in rent to break even. Its a lot easier, in most places, to get $1350 in rent than $3650.
Nice houses will work for flipping. But, you have to find an area where nice houses are selling for good prices, and where deals are available. My observation is that banks price their houses based on a move-in retail price less their estimate of fixup. If fixup is fairly minor, chances are good a retail buyer will come along and buy it. If fixup is large, like in your example, it may well end up setting for a long time.
My farm area has a lot of REOs and very few retail sales. But its very competitive as investors are buying up the REOs for rentals. Many of these investors have small or not so small companies, and have better economies of scale on their work than me. So, I have to look at a lot of houses and make a lot of offers to buy one. I had one offer fail this week, and two outstanding ones that are on life support, and a fourth one that just might work. But, I'm still going out tomorrow and look at some more and hopefully, make three or four more offers.
