Do you think I could rent those 2br. units for more money with this kind of bonus rooms? 

My opinion is that if you are going to be a full time investor and have the time and desire to look for deals, being an agent is a bonus.  

You might be able to find a realtor who will do it for free if you promise them a listing at the least, if not a bonus at 3.5/4% on their side.

They were paying medical people outrageous bonuses to move there. 

If they text the google voice number, you get a text.One nice little bonus to using google voice is you know when a call comes through google voice it's something you have to answer. 

If you buy another before the end of the year, you can do a cost seg analysis and take bonus depreciation. (80% for 2023)  Odds are the bonus depreciation will wipe out most, if not all of your capital gains from selling the 42 unit.

It may be to pay for a moving truck if they move out by the 15th, offer a small bonus - $200 - for exit within 10 days, something. 

I knew I would have tenants in place in August, anything before that would be a bonus.

Some ideas i had was to put a small kitchenette or to extend the un permitted bonus room to make it to a ADU

By opening a new credit card before a renovation project, you can take advantage of cash back bonuses and rewards that many credit cards offer.
