However, I usually include tax planning with my tax preparation fees and do not charge separately for the two.

They will charge extra for any extra work performed, but it could be much more beneficial than tying up that much equity in a partnership with someone you don't know.Also, if you ever do have a partnership, spend the money on the front-end with an attorney to get a sound operating agreement that makes the divorce less messy if it comes to that.

If you do have something you like that is monthly charge, please tell me that as well. 

Since 2020 we've been selling these units to individuals and organizations that may buy from 1 to 5-6 units each, but currently trying to expand our business.Given the interest rates for financing these types of structures and how much landlords are charging (for both short-term and long-term rentals), I found that the net income is way higher than the average mortgage payment, so basically it's free money.I've been thinking it'd be a good idea to partner up with a real estate developer to develop a mobile park.

Everything revolves around consistently receiving rent and having the ability to increase rents faster than inflation.

Please helpContact the district attorney/state's attorney/whatever and institute criminal charges.

In the furnished rental space, we charge a premium because our units are furnished.

If he stays anyway, most leases have a punitive holdover clause that would charge him bucket of money because he is injuring not on your property but also the incoming resident. 

Just because we do more doesn't mean we can always charge more.

If you are charging full 20 bucks it would give me pause.
