Due to population density and Building Code complexity, the fee is well earned as it's not a walk in the park to obtain construction permits.

There are more than one tax codes that are interconnected here and that is why you are confused.

Geez...that's like asking what do I need to know about construction, financing, valuation, municipal codes and permitting, Landlord/Tenant Laws, liability protection, marketing, tenant screening/lease contracts, running a business, market demographics/inventory/year-over-year appreciation/rent pricing - and a whole lot more.  

I know that area is not the best zip code to flip in, but depending on the lot size you definitely could have built and sold, or built and had it rented out!

In some cases the city will force you to bring it up to code or tear it down.

Given the current housing market situation, can you please recommend an area / zip code to look for investment properties?

But physically altering with infrastructure etc creates inventory and requires you to start a new clock to demonstrate your intent to hold for productive use and allow the 1031.

Has anyone used services like "Archinerds", "Southern Athena", etc. who advertise that they specialize in helping navigate codes and permits and refer you to building/remodeling professionals?

I was wondering if the posts I make on Facebook groups where I post a picture or 2 of the properties along with the zip code and brief description of them then ask if anyone is interested to drop an email below so I can send them the full info has any luck?
