We're going to tear out the drywall around the jacuzzi, replace it with cement board, add a shower head, and tile the surround.

There are definitely pros and cons to each so I figured I would just lay out a few benefits and personal thoughts: Small banks/brokerages:Pros:- Some regional knowledge of the market- Possibility of more creative lending guidelines with bank specific programs- Sometimes they have competitive rates for their areaCons: - weak balance sheet (more strict on some guidelines, no wiggle room, inability to be flexible or grant exceptions because they cannot afford to hold less than perfect loans)- Can't scale with clients to different markets- Usually limits exposure to individual investors (they don't want one investor to be too big of a portion of their balance sheet)- Lack of experience with multiple solutions (tend to have 2 or 3 loan products they sell and are too niche to provide tailored solutions)Large banks/brokerages:Pros:- Large compliance departments that understand individual market guidelines (typically each state has specific lending guidelines that augment the national baseline)- Ability to scale into multiple markets with same lender (licensed in many states)- Impossible for individual investors to "outgrow" a large bank's balance sheet (not concerned with one investor's concentration)- More lending solutions available for different scenarios- Often comparable or better rates given the game is volume basedCons:- Can be more difficult to get fast responses if the bank/brokerage does not have good follow up systems in place (or if the underwriting/processing staff gets overwhelmed)- Bad large banks can feel less like a relationship and more like a cog in a factory (less personal)Overall, I have worked from both and worked with both as a loan officer, branch manager, and as an investor/client myself. 

I could wait to do my renovations and just lay down new flooring for now and advertise for rent while waiting to purchase the other side, but that could hurt my appraisal, and refinance amount.

Just lay the ground rules, stick to them and let the tenant know.

Check With the attorney who provided the quiet tile or the title company that took care of your certificate.

It should outlast a tenant turn or two unlike carpet but no where near as hard to remove as tile. 

Had one flooring store recommend glue down, they said this is better than 20mil 5mm snap in LVP flooring, as the snap ins sometime break and you can easily replace a glue down.Another flooring store recommended "loose lay flooring" basically that is similar glue down, but has sticky material on each board. 

Being a 1960s era, it will have everywhere.  6 inch tile floors, hot water pipes, countertops, etc.Would check on that before diving in.
