Also, any CPA recommendations and/or tips on keeping track of expenses/documents?

Thank you for any advice, tips, feedback, comments, etc!

Do you have any tips, websites or general rule of thumb?

A win for the investor (which can only be determined by finding out what their needs are for being a part of this and nailing it), a win for you (purchasing an asset using someone else's money), and a win for the tenants you are housing (making sure you take care of each and every tenant ethically and with respect). 

I'd like to make more and I don't care how much risk there is.

If it is vacant you need to look very carefully at the market.

The way the bank finances an 8-plex and a duplex that you occupy is completely different so be careful with how you plan your purchase. 

If it is a 100 unit franchisee and they are putting only 4 stores backing your location out of the 100 that is different.You would then need to see the other stores sales and compare them for rent to sales ratio for health score with the business and then see if their stores are at,below, or above store average for the national brand.It's not just only the sales they are doing but the rent ratio.

Just be careful about where you are buying.
