Hi @Samuel Koekkoek it seems as though most of your questions have been answered.
My name is Adam King, I am a lifelong San Diegan. I have investments all over the city in multiple asset classes. Some cash flow amazingly, and some lose money every month, but they all serve a purpose.
As some have said, if you buy a Duplex your monthly payment after taking in rent from the other side will likely be close to what you are currently paying. Which for 200k or more down, may not seem like a great idea.
Conversely, a strategy that myself and several clients have used lately is value add. Find a duplex or even SFR that has ample room and zoning to add more units. Build extra units, at least one, but preferably as many as zoning will allow.
Doing this does 3 things to help you in the long run.
-Increases the Value of the property, almost always by at least the invested amount, in many areas of San Diego, it can increase the value of the property by as much as 150% of the invested amount
-Decreases your risk profile, having 4 units instead of 2, helps stabilize your rental revenue when vacancies and repairs have to happen.
-The large Capital improvement to the property greatly increases the basis for which you are able to depreciate the property. This tax savings can be huge when you are self managing, but still very useful for when you want to leave the state and have some property management company run it for you.
If you have any more questions, feel free to ask me. I would love to help!
