@Erik Peddle do you have an elevation certificate?

What may be required are things like getting a Certificate of Occupancy for the new units and inspections depending on local building codes.

Did you get estoppel certificates before you bought?

Hopefully, with Bigger Pockets I will obtain the right information to set me on the right track!

I would take the hit and find  licensed plumber and start entire process over and install "something" appropriate to local building code and obtain a fresh warranty. 

Can you please share how did you obtain the funds to purchase the property?

Until then I plan on finishing my Bachelor’s Degree in Real Estate Studies, obtain my real estate agent license, and eventually a broker’s license with the intent of opening a property management business in Southern Alabama.

All the info you will gain from those vehicles, you can obtain it here at bigger pockets for free.

I'm sure you can obtain the plan-sets for the homes from them when you buy (arch. engineering, electrical mechanical) to have them approved by your state.

My dad doesn't really want to sell but at present is basically only breaking even.My question here is twofold: First, how to obtain confirmation that the offer is good (independent of his manager, who seems invested in the deal)?
