There's the cost of the actual fix, PLUS the cost of managing and dealing with the project. 

As Chris mentioned, it's important to read the contract which should outline all fees the management company can charge for their services.

Well, first you find a deal that you can actually wholesale, then you approach the title & escrow company.

But if you’re fixing it up you might actually increase the taxes even higher. 

This would actually be my first flip. 

I worked with the one title company I found that would handle such a sale, and the sale was completed (with the help of Tax Title Services).I haven't bought any properties at tax-deed auctions in the intervening years, but I still look at the properties up for auction.

I have cleaning services and handymen/contractors and live near the property. 

Is it difficult finding actual businesses to buy? 

I have read many pros/cons about actually putting my property into the LLC. 

If you go with Ownerrez then pay for the ProConnect service.
