I’m having a difficult time trying to figure out the rent value of my 5 bedroom, 3350sf single-family dwelling in Oceanside California.

@Jason Merchey For more details, check out title 37, chapter 22 of the SC State law: http://www.scstatehouse.gov/code/t37c022.php (emphasis added):(30) "Mortgage loan" means a loan made to a natural person primarily for personal, family, or household use, primarily secured by a mortgage, deed of trust, or other security interest on residential real property or security interest arising under an installment sales contract or equivalent security interest against the borrower's dwelling and: (i) located in South Carolina, (ii) negotiated, offered, or otherwise transacted within this State, in whole or in part, or (iii) made or extended within this State.By definition, you didn't "make a mortgage loan" in the context of the legislation.

However, the seller claims he purchased the property as a two-unit dwelling based on Baltimore City public records, yet it’s not legally permitted as such.

In the parlance of the Federal government, such loans are called loans on one-to-four family dwellings.

Lead Certification billed per unit $200-$400  (depending on company you use) every 2 years3.HVAC Certification Billed per dwelling unit $100-$2004.

Here's what I find most interesting.Section 29-35-103(2)(b) of the ADU law says Colorado cities can NOT "require an ADU or any other dwelling on the same lot as an ADU, to be owner-occupied."

Even though this wouldnt be purchase money financing, ultimately your loan would be secured by a dwelling, rather than by real property owned by a commercial entity for transactional purposes.

In my city's codes and ordinances it states that one of the common rental property violations is having "over four unrelated individuals residing in a dwelling unit" would the dwelling unit be considered the entire house or just the part contained in the lease (aka the room)?

Looking to start with house flipping and eventually move into multi-dwelling property as a more steady stream of revenue.

The main pro for building would be the ability to control where I live while living in the house, whereas most multifamily homes are within city limits and not my preferred choice of dwelling.
