It takes lot of hard work to work with an investor. Most of the Agents treats investors just like regular buyers. The difference between a retail buyer and in investor is the buyers buy on emotion and investors buy on numbers. Buyers need a dream house, investors need a profitable house.
As a Realtor, you need to know the numbers to work with an investor, like actual ARV, marketing conditions present and future(in 6- 12 months when that property ready to sell after reno), average reno cost etc.....
Do not tell the investors that there are other offers on the property and if you don't buy it today you will loose it (if the numbers wont work). If an agent tell me that, I know that agent is not an investor friendly agent.
Investors are very busy. I have some agent put me on auto prospect list feed. I cut them off right of way or will not talk to them. Prospect match emails are for buyers not for investors.
If you have good five investors, and if you feed them with good properties, your life is set. It takes time and dedication long working hours to find good properties for investors. You need to find off-market properties, cant just depend on MLS.
Good Luck
