I actually ran the numbers even up to 10% vacancy and increased the maintenance and it still makes money even if it gets that bad. I am not a seasoned pro at calculating this to death. I did request my realtor send me the numbers/spreadsheet they use. They ran the numbers and they looked good to them, but I want to double check what they use for the area against what I have tried.
I don't expect the taxes and insurance to move much, but I am going to go double check the county records to see what the appraised rate is. It is is rare, but maybe I can argue them down based on the purchase price :) They generally under appraise and over tax to seemingly erase all good arguments! I don't expect them to be appraised far off.
Those numbers above are not actually mine, but ones someone else created. I rarely go over 1 month on a vacancy around here and typically have relatively low turnover rates at my other properties. It does not take more than a few showing typically. I try to keep my properties nice enough that I would live in them. I think all but two are way over the 1 year lease (some of them above a decade). I have at least 3 lifers I think. I have had more than one unit where they lived there until they died. Usually a sign out front is the extent of the advertising. My stuff is all in a peaceful rural environment near smaller towns, but within an hour of a large city.
I am still messing with the numbers, but so far nothing is scaring me too much. Everything has some risk. This is the best deal I have found in my county since I have started looking. SFH are all priced out of doing anything and the fixer uppers available are really more suitable for demolition because they are hacked together improperly built junkers. I looked at two Saturday. Garbage. Decent houses can't command enough rent to justify the prices. You can pretty much forget finding anything that comes close to even the 1% rule in SFH's around here unless you want to get in the the big city in sketchy neighborhoods.
One thing I like so far is that all my rentals are within 15 mins of where I live and even closer to my land I plan to build on again some day. I don't know how anyone buys far away. I can never find anyone reliable or reasonably priced to work on anything around here. This is always my biggest challenge. I consider the renters and the rest pretty easy. It is the maintenance that is so painful to get done.
I will take a pause after this one to see how it goes for awhile and rebuild funds. If there are any problems, I will still have this purchased at a very low price for it's construction (under $64 Sq/ft). This is a nice place in a low density, but still slow growing area. I know this area well since I have lived here all my life. I don't feel comfortable buying far away or something I can not go fix something on my own if I need to.
As for insurance and snow, there is no way around these risks. I do snow removal when needed, so that is all you can do. I usually just pay a guy $50 bucks to clear the drive at my other rentals as needed. We really don't get many snows where it lands and lasts long. I did not do any plowing last year. However, I also have a side by side with an electric raise/lower Warn snow plow :) I can do my own if I need to. I did loosely figure for there to be some snow removal and the snow removal on the main subdivision road is part of the maintenance fee.
I do have my stuff in a proper LLC now and I do carry regular insurance. I may consider buying an umbrella after this just to add another layer of security. There is no such thing as risk free. So far so good though and I have been doing this for a pretty long time on my other 6 units.
"Do you get higher cap rates in college towns like Rolla, Columbia with 20% down?"
I doubt it, but I have not fully studied it. I do know people that live in both of those towns and the prices seem similar to my area. I consider these too far away for me though.
I would not consider this area a hot market at all for outside investors. It just happens to be where I live and invest (right or wrong). I think if your not living here, it is probably an even tougher market to get into. A lot of people that seem to be landlords in this area either built new, have owned them for decades upon decades, got them from their parents, or are slum lords. It is hard to start from scratch and do much in this county I think.
I guess my goal at some point is to possibly become independent of my day job and self manage/maintain my properties myself and just make all the money :) I have all the trade skills necessary to never hire anything out if I had more time. Who knows what the future will hold though. All I know is that sitting around doing nothing gets you just that......
