Welcome Derrik,
I think its great that you can do a lot of the work yourself, but pay yourself for doing it.
Same goes for property management. Do it save the money learn the process but pay yourself. Plus what happens when you move or have to many units to manage yourself? If you calc. for PM it should still cashflow.
Another big ticket item you left out is cap ex. Repairs are Broken sprinkler heads and leaky toilets that happen all the time. Cap Ex is the 30 yr roof with 7 yrs left and water heaters and furnaces with ever shrinking life spans. Windows, cabinets, appliances and floors ect. These don't come up every year but saving 10% a year sure helps
Im a new investor as well so I like to run my numbers over the top conservative to cover the oh sh** moments I didn't think through. Be careful not to talk yourself into a property that doesn't make sense, it can be easy to do. Especially when dealing with family.
Its funny, I bought in Yakima because I couldn't find cashflow in Napa Ca.
Good luck
Casey
