OK I do have a little expertise in CA on these issues..

But hearing your expertise is super helpful  as it's relevant to us here as we start our investment journey into MTRs.Have you had your place 90% rented most of the year, or have you experienced blips in vacancies?   

Where people went cheap with online brokers, many of those companies just did not have the resources or expertise is seemed in many instances to handle claims. 

You put up the money, they lend you their expertise.

So you definitely need to have good boots on the ground with nuanced expertise. 

Even units in the rear, not visible from the front street are not allowed to be residential and must be commercial.

SBA loans can be used for new construction, but that's not my area of expertise so I can't be too helpful there.

Quote from @Kar Sun: My tenant's lease is coming to a close and I am relieved she will be moving soon.She has been paying on time but has been extremely unpleasant and rude.While the money does not smell my mental sanity is more important than money in this case.She sent me a registered letter stating that she feels "unsafe because we have not done the fixes the way she wanted it".She requests to have her witness for a walkthrough.In my state a walkthrough is required but I am not about to grant it to her to bring any witnesses as that is not in my contract.If she feels unsafe she does not have t be present.I also do not treat a final walkthrough with a tenant as a final sign off.This walkthrough does not include a detailed inspection of the plumbing and the appliances that will be done after she departs.This is simply for the visible cosmetic issues and should take less than 1 hr.  

It’s fantastic to have a Realtor and investor with expertise in new construction homes joining the community.Here’s how you can engage and collaborate with the BP community.

Where a good (operative word) agent's expertise comes in is doing all of these things and doing them all well, and not missing anything important, and also a million other things behind the scenes that protect their clients from being ripped off or sued or just wasting their time learning all the ins and outs of real estate transactions when there are experts they can easily hire to handle it all for them.
