3) How flexible is the contractor about meeting at the property for their inspection to generate a bid? 

Quote from @Raif Jochim: Bigger Pockets Community -I'm trying to plan for the future and have a question I'd like your thoughts on.  

When a tenant moves out, transfer the deposit back to Checking so it's ready to apply towards expenses or to refund to the Tenant.If you end up with excess funds in the Checking account, I recommend you transfer it to a third account that is specifically designated for future investments.

If interested, DM me and I can connect you to the organizers so that you are aware of future meetups.

I'd like to add another SFH to the business  in the near future with the main goal being grow the business as fast as possible. 

Go out and start making your future come into existence. 

I want to look into the possibility of a future ADU there as well.

From then I knew real estate investing would be in my future.

I don't think the future will be kind to the investors who bought cheap houses in a big community of other investors. 

I would recommend looking at a loan with a short prepayment penalty if looking to get cash out, that way you can refinance again if rates drop again in the near future.
