I have 2 sales people in my office and 1 tech guy. 

They are a realtor office.

Research the County Clerk / PVA office for LLC, and individual names that have a bunch of properties listed under their names good way to identify landlords w/ multiple properties.Just a couple of ways to find package deals. #2 is also a good way to find off market deals which is where you can save the most even if it's just buying a house direct from the owner w/o an agent.  

I just landed an internship in a zoning office and I have been doing it all to raise funds to put towards my first investment property.

We turned the 2 bedroom, 2,000 sq/ft home, to a 5-office, property with a kitchen, two bathrooms, a parking lot and a backyard.

When buying a prop, with a tenant already in, YES, get a copy of the HAP, agreement and lease, Call the office and make sure all is in order, DO NOT trust the seller.

If you find a local realtor and loan officer who specializes in investing in your area, start having conversations to get up to speed on your market.
