Presumably someone does your tax returns, ask them.

Some things to consider are: if minor maintenance is included, if they file the occupancy tax on the owners behalf, if they hire the cleaning service and if they "eat" the credit card fees or pass them onto the owner.

An added bonus is that you will also boost the portion of your payments going to interest, which increases after-tax cashflow. 

Most properties in my area have property taxes between 3K-4K.  

You can cash out refinance, allowing you access that equity tax deferred. 

A local credit union also mentioned something called a "savings secured loan" which can be used for anything (even going on vacation), but I don't know if there are tax benefits to that and I don't think I can do that under an LLC.  

I suggest Nevada because of the proximity to CA, landlord friendly, and low property taxes.

Say a 550,000 loan with 25% down at 10% interest on 15 yr vs 30 yr. 15 yr monthly payment-- $4,40030 yr monthly payment -- $3,600Does not include property tax 

Current expenses are $1300 per month (water, sewer/septic, taxes (property and 10 homes) and insurance (liability and homes).   

The tricky one is the rent to income ratio and how it is related to the median family income.I did note that at lease one other poster was advised to always use the low barrier screening criteria to avoid potential lawsuits.
