I'm mostly interested in buy and hold rental properties to generate cash flow, one at a time. on investor side.I'm also excited to help buyers/investors to buy properties in Silicon Valley, Santa Clara County, San Mateo County and Alameda County. on Realtor side.Looking forward to learning from every one of you!

The investor said the only expense the buyer of this house pays is the closing costs.

I have my first closing this week and am very excited but was wondering if I should/need to attend closing or should I just let the end buyer and seller go?

Spot on and this is what we do with our tenant/buyers. 

I would pick a realtor who owns rental properties and someone who it's too new in the business or too old.If a realtor owns rental properties themselves, they automatically have experience your buyer is going to want in a realtor. 

The deal gets to close on time, the work gets done, the work inspected to the buyer's satisfaction, then the money is released form the Escrow.This can work just as well for open permit issues and other paperwork that might take too long.Anytime you ask for repairs, you risk holding up the closing.

First time home buyer looking to house hack in the Napa valley where we live.

Most agents here in CA are now charging 2.5% to the seller and offering 2.5% to the buyers agent.

Have the buyer pay for your lawyers fee to draw up the mortgage.

Remember to target people with last market sale date of 3+ years - this number depends on how much the market grew but you are really trying to avoid cash buyers from the last couple months/years, they won’t want to see it :)
