By budgeting $0 for any up-front repairs, you're banking on the best-case scenario happening and not leaving yourself any margin of safety in case a less-than-best-case scenario happens.I also see you've budgeted exactly 3.5% for the down-payment. 

I have purchased vacant home insurance before when not flipping but when getting ready for tenants, and it's generally extremely expensive, I had one policy that was about $300 a month for a SFH (we only carried it for 6 weeks and then switched to landlord.) 

Safety comes at a price.

It's a Scorch the earth policy. 

But like the person above me said “no one checks” but i would tread lightly with that because of home owner insurance policies and liability issues.

Also this unit is just the first year after the HUD safety laws came into effect in 1976.

Alternately, you could charge "pet rent" - I would do whatever is the local custom in your market.I would create a pet policy you are comfortable with. 

You need to make sure you have good insurance or even an umbrella policy for your homes. 

Looking for the most cost-effective policies for my 4 rentals in KC area.Any help is appreciated.

I am not worried about safety issues for my future renters since the space has been inspected and construction is good but just thinking if it is even possible to obtain permitting after the fact?
