I feel for you. 

Quote from @Jonathan Beaumont: Good morning.I will be responsible for collecting rent and paying bills for two small apartment buildings.

What laws would hinder the creation of apartments where residents are required to own and open carry firearms . 

Because they will get defensive if they feel you are pressuring them.

@Andrew Foster some decent advice here, but also some feedback from those who really don't have enough info to support their perspective.Many DIY investors price repairs on materials only and forget about labor as they do their own work.We're a PMC in Metro Detroit, but here's how our process would work:1) MoveOut Video & Pics used to create Scope Of Work (SOW)2) SOW broken down into Priority Categories:- Health & Safety- Government Required (municipality/S8 inspection requirements)- Property Preservation- Marketing Impact / Tenant Retention- Miscellaneous3) Bids obtained if we feel work will exceed Owner Approval Threshold4) Bid sent & discussed with owner to, "redline to their budget"5) Work begins once owner approves & funds6) Completion video/pics providedOf course, while this is going on our Marketing Dept would be doing a rental analysis & ad, and discussing with owner.

This gives us time to do the backchecking so they don't just flit off to the next place and change their mind in the meantime, and they have the apartment reserved.

I live in North Dakota, and I came across an apartment complex for sale in one of the state’s oil-heavy cities.

@Ana Booze, typically your local banks and credit unions are the primary lenders for "mid sized" apartments, in my experiences. 

I have 950 square foot two-bed apartments in Euclid OH.

Here in New York (City and Suburbs), a 2 bed/ 1 bath apartment is on the market for about 1 month before being rented (Median DOM = 29).The time of year is also something to be considered.
