If they're overcharging you however, then I'd suggest getting a new management company, as I don't believe that's an ethical way to do business.  

It's allowed me to do some of my own work like changing toilets and fixing leaking ceilings, but even if I don't want to do a job personally hopefully I'll have enough knowledge to not let a contractor over charge me, or recommend something I don't need.You'll also meet local contractors, and hopefully investors.They may offer an employee discount too.

It does not answer every question (are they under/overcharging, do they have egregious cancellation terms, do they have silly rights to sell your property, do they have two and half pages of ticky tack fees, etc.), but something has to go reasonably right for a PM to have 95% occupancy or greater on a several hundred unit portfolio, in my view.

Contractor: Finding contractors that don't cut corners and overcharge is EXTREMELY difficult.

Property manager Oz Realty tried overcharging me for maintenance costs, and refused to produce invoice for any work done.

BRRRR is great but chances finding a deal and getting all your money out with light rehab is slim to none unless you find your own lead.I operate in Baltimore in C+ areas which is still cheaper than many even wholesalers are overcharging for their off market deals.You either have to do heavier rehab or find a deal without a middle man.

We hired a plumber (that we have used for years) to fix a tub spout leak and toilet repair. They fixed the toilet with no problems. They installed a new cartridge for the tub but it was still leaking. Said they would ...

I wouldn't expect a huge discount...well if you do get a huge discount, they were most likely overcharging you from the beginning.Good luck with your negotiating!

Can anyone recommend a trustworthy inspector who is not going to overcharge or create unnecessary problems?
