Investors are just like other tire kickers too, they may act interested just to see the deal but not have the cash to allocate to it.

My guess is yes, but you cannot hold more than 1 month's rent as security deposit and the amount collected must go into an interest bearing account (which is .05% today) - 1 account per tenant OR you have to keep track of individual interest allocated if you co-mingle money.

The thing I would question or alter is your breakdown for personal day-to-day expenses and whether that could be reallocated more aggressively towards investing in your business or other streams of income, which could also be dependent or influenced by your "other streams of income".Ultimately the allocation should depend on your business and investment goals.

Make sure your agent knows what he or she is talking about and can properly help asses cost.I have seen properties with 10% of rent roll allocated for CapEx and Maintenance when the real number is 30%

Lots of options in So Cal for these types of investments, I would say the first thing you want to do is to start narrowing down what type of investment you want to make first and how much time you want to allocate to your investments.

As a matter of fact it's a great way to combine the favorable financing of a primary residence with the purchase of an investment property.When that property is sold you'll be able to take the portion allocated to the primary residence tax free (providing you've lived in it for two years).
