Do you know how to "inspect"?

and then get find someone for me to do a inspection on the house etc, or do i need to go through a real estate course and learn more.

Quick contract, nothing major during inspection, buyer is solid and everything closes on time.

I use David Armstrong, he has done many inspections for me.

Don't want to rain on  your parade, but success is not in these kinds of numbers and being too aggressive too soon with so little background, you're headed for a great disappointment IMO.Assuming all your acquisitions come true (1,2), you will need a team to manage the units - - heck, you'll need one full time employee to just process tenant applications, and move-in/out inspections. 

For houses that you're actually going to inspect, you have to go inspect them and make your offers right away because someone else is. 

Will also do reduced rate inspections for investors. 

Whereas if you have it under contract and the repairs come in higher after inspections, etc, then you can ask the Seller for concessions based on information not disclosed, etc.You will get better at high level estimates with experience, but until then you have to make an educated guess and then firm that up with bids after you have it locked in.

The only reason I'm selling is due it being a class D property/neighborhood, and I'm looking to improve my portfolio class, and id rather not fix anymore bullet holes.Buyer did inspections and came back with a laundry list of repairs, trying to justify a low ball reduction to $70k, minus 5% comm.  

Pictures, inspection reports, video, and a property manager is all he needed.
