My goals (with my limited knowledge) are to do fix-and-flip deals to earn money and then reinvest in buy-and-hold properties.

I've been fortunate enough through my research and what I learned here on BP to have bought a solid investment property, which of course started with having the knowledge to identify and recognize the opportunity for what it was worth and act on it.

If its a D class neighborhood then depending on what I started with and what I paid to make it "better" I may just let it ride "as is"..... the extra $$ I may have to pay to make it better just isn't worth it in that class of rental.

You are probably getting more knowledge and experience when working with a broker but this isn't always the case.It is best to just find someone you like working with, brings you good and useful information, and bring you deals.

It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

Also you need a job that produces enough money to live off of and have extra to invest plus have the flexibility and time to invest and network. 

A couple months vacancy during a turnover would pretty much wipe out the extra money id get from not negotiating.

As the Property Manager for a landlord, do you folks charge extra for any repair projects or maintenance calls that require on-site supervision and time spent above the normal call of duty to see the repair or maintenance through?

Thanks in advance for being open to share your knowledge!

The ultimate question would then be, what is the payback period (from maintenance savings) for spending the extra $470/unit to vent outside?
