So I may not have gone the best route with my first 5 SFH. The first one was new build; bought direct from the builder, we bought it to live in. A few weeks after moving in my wife said she needed a bigger house....didn't want to sell it to take the loss, so fell into being landlords and have had the same tenant since we moved out in 2016. At the end of the year I thought I needed to get another one and bought in a nearby subdivision from a major builder who was trying to clear stock after a bad year in sales for them, so got a great deal. Had an immediate renter who's been there ever since. We liked it so much we had them build another one up the street for us for about the same price. 2 years later we bought another new build in the same neighborhood, and another new build in a different neighborhood. They've been going well. The numbers work for around a 5% return. Not making me a millionaire, but like you mentioned, little or no capex. I've had 2 AC repairs, 1 ceiling fan which I replaced myself, and I put in 4 power outlets for the longest term tenant.
I like the neighborhood, it has a good school district, everything is new, close to the highways, and attracts a higher quality tenant and higher rent. The AC units are not in cages, that's a good sign. Easy to offload too since they are in the desirable area.
So bottom line, would I repeat these 5 purchases? As I get more experienced, probably not. They are a great, safe way to ease your way into this. I'm very happy I have the ones I do as they are cash flowing with low headaches (capex). In fact, the biggest headaches I got, were from my property management company just being useless, incompetent sacks.
One point I saw mentioned was the 6-8 month delay with no return. When you buy a new build, in my experience with a bigger builder, I put down $5K I think it was, and not another dime til they handed me the keys. So return wasn't the issue, there was just the cash flow delay. And then there's the other part of 15-20% down, or around $40K in my deals.
Others are building portfolios faster doing flips BRRRRs, etc. There's a lot of variables, mainly how involved do you want to be vs how much do you have to be based on finances.
I would recommend doing it, especially as a first property. Good luck
