Modern codes might require 5 in a room like that.

Quote from @Hector Espinosa: Hi,I'm negotiating a seller financing deal which may be my first one and would like to ask for some advise about and what are advantages and disadvantages about seller financing deals.These are the seller financing terms:House Price: $330,000.00 USD​ (Sellers still owe ~$301,000 USD)Down Payment: 5% = $16,500 USD​Loan Amount: $313, 500​ (Monthly payments will be amortized as a 30 years loan​)Interest Rate: 4.531%Balloon Loan Term: 5 YearsMonthly Payment (P&I): $1,594.24​Closing Costs:  ~$3300 ​Zip Code: 74105Observations:       * HVAC requires an update but pending to inspection (replacing with a new one will cost ~$10,000 - $15,000 USD )     * Expected Rent Income: $2,000- $2,300 but this is has been really complicated to get a good estimate because is all over the place in the different sites I have checked

I am thinking I'll have to set aside expenses to redo the wiring, plumbing, etc and bring them upto code. 

My property is in the Homewood/Vestavia area...35216 area code.

All the bylaws, building codes and fire codes can be found on the city website.

Because these communities would be in smaller towns and rural communities, the licensing jurisdiction is the county, meaning that code requirements are more often vested in the fire marshal and are less onerous than city requirements for the buildings and the site improvements.

Both programs can aggregate data based on filters like zip codes, sell scores, etc. 

Go on Zillow, type in your zip code and the bed/bath count, and see what is currently for rent.

Code Enforcement in my market has just recently started, as part of their tenant turnover inspections, to document the material composing the water inlet pipes where they enter into the basement.
