What scams should I look out for and avoid?

You all ready have a jump start on most of the newbies I encounter, most just ask me a lot of questions with no retention what so ever.

Lessons:  1) Don't like the answer, go elsewhere multiple times, 2) no mega banks, 3) work with a friend to fix small stuff that comes up, 4) VA loans can be used on more than one home so long as don't exceed the cap ($453K) however, VA funding fee is more each time and there are other rules to follow with intent and occupancy you need to be informed of  5) some mngt companies are passive in repairs, checkups and finding tenants (due diligence and ensure they meet your criteria instead of you meeting theirs 6) rental and appreciation markets vary drastically from place to place...your #s and analysis must adapt to the area, 7)  around a bustling base or post...use creative marketing to attract your target audience because you speak the language to a large portion of the people coming and going.  8) If you use mngt company...help them succeedThere are allot of scam artist companies that capitalize on the dependency of a relocating Mil families...while giving poor service with a smile just to sell something. 

@Julie McCoy @Mike ReynoldsSince I started doing STRs to contractors 6 years ago, I have encountered only 2 employers that make motel reservations and pay for their employees rooms ahead of time. 

It affects it, whether one realtor has not encountered anyone that outright told him it affected their purchase decision.......In high tax states, the deduction factors into peoples purchase decisions because it affects affordability, just like INTEREST rates do..... 

I had prospective tenants tell me they screen properties for a scam by driving by the property they find online to see if there is a yard sign.

I am having trouble hearing back from the seller on some of the costs of the property so I'm trying to get a sense of what costs I might encounter.

Once you get your feet wet, I would agree commercial properties are more likely to maximize your potential cash flow but you will likely encounter more headaches and issues and require much more capital.

Too much "fluff" and I think you're out to scam me with BS. ;-)
