Never twice.I recommend you start a relationship with an accountant, since your understanding of taxes is shaky.

Here is my situation:I open an LLC for each of my investment properties and for each LLC I need a bank account.I do not want to go down the route of using a traditional bank and open a new bank account with say Wells Fargo unless I have to.I have tried baseline banking which allows you to open one "account" and have multiple accounts within that (one for each LLC).

You want an accountant that can help you strategize and who is responsive when you want to know the tax consequences of the decisions you are making throughout the year.Good luck in your search.

Also, I don't see why you would take the risk of buying it in your own name and moving it into an LLC later...If it's a matter of the bank only taking your personal financial situation into account if you do it in your own name, I'd personally rather use hard/private money to acquire it, then refi with a bank once the property financials stand on its own.

And when you account for appreciation that doesn't appear to be changing in the next few years, you could lose more by waiting a year for the "best deal" instead of paying $10-$20k more right now and starting to save from your house-hacking venture. 

Every $100k in gain up to the limits, $250k (if single) or $500k (if married) will save you $15k in federal taxes and I’m guessing $5-10k in state taxes?  

You can avoid taxes on $250,000 in gains if you are single and $500,000 if you are married.

Water bills come in once every 3 months and I give tenants ample notice prior to updating their accounts with the water bill charge.

I own a few single family residence rentals, and I am in the process of transferring them to the LLC that I opened to hold my properties. 

I have owned single family section 8 rentals in the past, and while it was pretty straight forward, each jurisdiction likely has their own requirements and processes.In Cincinnati, again, I was buying properties on the MLS, they used to (maybe still do) use gosection8.com for LLs to list their properties.
