How much should a general contractor charge to allow my company to pull permits for each renovation and how much should he charge per onsite visit to spot check subcontractor work?

Spot development usually drags everything down around it.

I will eventually buy in the Columbus market but for now, I found a sweet spot. 

I’ve been spending a lot of time on Bigger Pockets and reading articles to prepare myself before I begin - but I’m at the moment where I feel I am in a great spot to start.I’m interested in finding a fix & flip property in the Metro Detroit area that might offer a good opportunity.Any tips, tricks, or advice for a beginning flipper?

It doesn't take long to learn how to spot a good deal.6.

Would love an update if you decided to invest, and if you picked a different spot, would love to know why! 

Every market has its bright spot its great Agents and PM's etc.. its all personal choice.

Purchase: $80k-$130kRent: $1100-$1500 (no rent control in MI)1% rule: 1%-1.4% rule dealsROI: 10-14%Cash flow: $150-$300/door (after all expenses and budgeting for maint, capex, vacancy)Appreciation: 3-10%+ (has been double digit for a decade)Location: C+, B- These numbers are based on the “sweet spot” in Metro Detroit.

You are in the right spot for sure, but this post is just a vague announcement.

Making tenants 100% responsible as @Nathan Gesner posts is spot on.
