Hi, Jennifer,
You bring up several points I've seen discussed and learned from here on BP. Being on the west coast as well, I have a similar situation to you. Here is what I have learned:
If you want cashflow that you can add to your income and, more importantly, cover maintenance and Cap ex and vacancy, then anywhere on the west coast - especially CA - performs poorly compared to other markets. CA is an appreciation market, which is a speculation game. Plus you would be tying up all your capital in one property, thus increasing your risk during vacancies when you have no rental income, but still a hefty CA mortgage to pay.
Concerning cash purchase vs. financing - that's a big debate topic on BP, and each person's situation determines what strategy is best, but for folks like you and I just starting our RE investing careers, financing has a lot of advantages. You can get more bang for the buck (able to purchase more properties), tax advantages with interest deduction, and are only spending your own money in the downpayment while trnants pay for the rest of the property over time, but don't enjoy the ownership incentives you do. If you pencil out a side-by-side comparison of slapping down $100K on a cash purchase vs 4 downpayments with the same money, you might find your 4 leveraged houses combined provide you more cashflow that your paid for property, taking vacancy, maintenance, and depreciation into account.
Concerning out-of-state investing, consider looking at the reputable turnkey companies friendly to out-if-state investors in lucrative markets, like Memphis Invest in Mdmohis, Dallas, or Houston; companies in Indianapolis, Cleveland, Kansas City, Birmingham, or Fl. A top notch turnkey will manage your rentals for you without your needing to fly out all the time - see what other BP members say about this.
Concerning properties in the $30K-$45K range - I suggest you look at a $60-100K range. Those tend to have higher cash flow because of less vacancy, maintenance, and fewer deferred maintenance items. The higher rent these attract also attract higher quality trnants who take better care of the property, and let you have a much more passive income stream.
Putting all these aspects together, you could for example buy 3 properties in another state financed with 20% down and averaging $200-$250 each month with little action required of you.
Hope this helps!
