However, if you want 3-5 fully paid off houses in 20-30 years to supplement your retirement, then putting a little more down makes sense so you're not having to fund the property out of your personal cash flow. 

I'm new to California and I know the state is not landlord-friendly so I think its hard to raise rents to market value (max I can do is 10%) is that right? 

You can't keep raising the rent $50-$100 ever year. 

Has any one ever used Limitless Funding Source?

It's fairly high profile and owner wants tenants to provide proof of funds and concept prior to getting access to any info.

Also interested in entertaining funding for those if possible.

It's also very uncommon (perhaps just socially unacceptable) to raise rents/prices.

Purchased for kids future/college fund (maybe relevant maybe not) Mortgage rate is 4.4% currently paying $1149 a month (including taxes/Insurance)Currently rents for $1550 (room for upping rent to $1600+)In the 2 years Ive had it, Ive added a roof(insurance claim),new windows, new bathroom, plumbing.

Each investors experience could be different, that being said Capital Fund One is a great pairing for me.

The junior deed of trust has an outstanding balance of ~$700k (will be wiped out via the foreclosure) and there aren’t any overbid funds for the holder of the junior deed of trust.
