I did increase by $100 back in covid when rents jumped $300 to $500 in 6 months.

Personally I would take as little as possible to meet my needs and invest the rest.However there are tax considerations.

Max occupancy is 8 and higher than that requires special consideration.

Minimal or NO rent increase this year. 

You can submit a rent increase every year.  

You could hopefully create cash flow with the house and cut your living expenses down considerably with the rent from the other side of the duplex.

Also you can increase price by a certain percentage whenever there is more pool usage - spring through fall and during major events/ festivals - this will help with pool upkeep.

 $100 rent increase is $1200.  

I would say the pricing reset that occurred a few years ago has to be taken into consideration along with increasingly demanding building code requirements that continue to go into effect across most of the country.
