This property has some one-of-a-kind qualities namely a nice creek with inbound and outbound waterfalls at each end of the property (its on a hill w creek canyon).I've gotten the septic scoped and certified, well is good, power needs to be reinstalled as property was abandoned years ago.

The plumber’s report indicates that the leak may have been caused by an overflowing tub or sink upstairs, but the tenant in that bedroom denies any such incident.As a result, I now have substantial expenses for the plumber and restoration company, including drywall repairs, painting, texturing, and reinstalling electricals.

@Nathan Frost typical for Detroit, that's why we offer our clients several security options, including removing & storing mechanicals when vacant and then reinstalling day tenant moves in.What makes you think the seller will install new mechanicals?

We want a camera system that:1) Connects to internet for remote monitoring via an office computer (not just a mobile device)2) Has motion-sensor alerts3) Records to the cloud, so a thief can't disable/steal the camera to hide their identityWe plan to remove these cameras once a property is rented and reinstall at the next vacant rental.Wi-Fi connection to internet is possible, but we'd also like to look into cellular connections to internet.What suggestions do you have please?

If you have to replace your roof, you will need to have the panels removed and reinstalled by an authorized solar installer - quite probably the same company who installed them in the first place.

You will likely have cracked drywall and porches will have to be re-installed.

Why are you re-installing mechanicals on vacant properties - after they've been stolen?

But if you just replaced kitchen cabs and counter without moving any fixtures, and same for bath (left tub alone), then it’s much less work not needing to remove and reinstall Sheetrock, not to mention the plumbing and electrical work. 

Reinstalled firware.

This home had a HUGE delay that cost us thousands of dollars.The group that put in the underground plumbing dug the plumbing too low, and by the time we caught the mistake, the slab had already been poured and the septic tanks installed.We had to dig up the septic tanks, install a lift station, and reinstall the septic tanks.This all happened during 2 hurricanes, which caused even more delays.Time kills deals.This is why you need to 1) be conservative with your timelines and costs, 2) add contingencies to your budgets, and 3) have a healthy profit margin.
