@Dan H. You are bringing up interesting points but almost all of them have to do with poor due diligence and being prepared and would result in failure locally and out-of-state.
You mentioned that you do not know anyone that have failed in your local market which apperas to be CA. Are they buying only for appreciation? How will they fare if the market there cools down after 10 years of extreme growth? Why would these investors fail out-of-state but not locally? Also do you know any out-of-state investors? Why did they fail? Would you partner with these investors locally or out-of-state? Reason I am asking is that there has got to be a reason they failed and unless extreme bad luck that can happen locally as well, it must have been their research and due diligence that resulted in failure.
Self-manage. True, if you have time, knowledge, and want to self-manage, that is something you cannot easily do out-of-state but it is a simple fix out-of-state by having a knowledgeable property manager and account for it in your analysis. Frankly, if you are planning on building a fairly large portfolio, locally or out-of-state, you should account for property management fees anyways because at some point it will be impossible to manage unless you do it full time. Personally, I have no interest, time, or knowledge to self-manage so I would account for property management fees locally and out-of-state. And I don't think you should EVER get into a "borderline" investment - that is setting you up for failure anywhere. Have set criteria and follow it.Have enough safety to protect for unexpected events like eviction, lots of capex needing fixed early on etc. I would whole heartily disagree that a local investor have an easier time finding people that can fix problems with a property. I believe the process is the exact same whether locally or out-of-state. You need to do your research, compare prices, and talk to people in any market. It is about building a network. Personally, I have not noticed much difference networking locally or out-of-state, same process, and equally time consuming.
For capex discussion, like you mentioned that occur in every market - locally and out-of-state. I hope everyone has a detailed spreadsheets or some way of determining total capex (I know I certainly do), but I doubt it... How did you get to your capex numbers in your local market? Unless you are a contractor or have significant experience with material and labor, I assume you studied prices of material in stores in your local market and called around to get estimates for various capex until you found reasonable estimates? That has to be done locally or out-of-state unless, again, you have knowledge of such data in your local market due to experience or work. I did not have this experience locally or out-of-state, so had to do my own research and talk to people to come up with my spreadsheet numbers in each market.
"In lower class properties I see items not accounted for such as no payment is different than vacancy." I would argue that someone investing in California are much more likely to invest in a low class neighborhood than someone investing out-of-state simply due to prices. Someone that has limited funds and is told to invest locally in CA for example, do not have a choice but find a an area that few are interested in (less appreciation and no cash flow) or D neighborhoods. That same person can take that down-payment and go out-of-State and find an A or B neighborhood that brings cashflow and is expected to appreciate and can find much better tenants IMO. I just don't understand why people assume that out-of-state investing equals warzones or D class neighborhoods. If you do a little bit of research and networking, you can easily find places out-of-state that will provide cashflow and appreciation in a great location.
As for appreciation, I hate to rely on appreciation alone and refuse to have negative cash flow and bet on appreciation, doesn't make sense to me. Appreciation in your local market works until it doesn't. And if you bet on appreciation, what about people that live in areas that have poor appreciation?
I believe a lot of people have a misconception about out-of-state investing because they hear a horror story about someone being taken advantage of or because someone didn't do their homework and did poorly. I bet there are many such instances locally as well, just not talked about the same. Just my 2 cents.
