We have a line in our lease addendum that states if the tenant wishes to break the lease that they pay a one time fee equivalent to 2 months rent and forfeit their security deposit.

Less security and harder terms for your buyer from a lender when you sell.The real test on the strip center is the quality of the location and demand for a spot.

When tenants move and I return security deposits, should I divide the deposit equally among the tenants and write a check to each tenant and give an equal amount?

Second question is whether security deposit should also be charged on credit card or is it better to request a check?

Should I take the security deposit from them or closer to the moving date?

I think in any case, it is proper to require official documentation to make sure they're registered to do so:http://www.massachusettsmarijuanacompliance.com/ma...I'd never heard of manufacturing dabs/wax. 

Focus your efforts on what ever is necessary for you to find a job that will be more secure.

Definitely consult with your CPA about this as you may have specific situations that didn't come up in your post.Generally, there is an advantage to running businesses like property management or wholesaling through an LLC taxed as an S-Corp, as it can save you social security taxes (your CPA can run the numbers for you along with a more comprehensive tax plan).However, it's usually a bad idea to hold rental property in an S-Corp, so you probably wouldn't want these two revenue streams (rental and wholesaling) running through the same entity.Let me know if you have any questions!

But what if a bank could give me a secured loan up to the amount of my documented contributions, while also holding that same money as collateral?

We have 1st, last, and security deposit.
