What type of coverage? Could be age, type of construction, location. If the coverage limits are the same and you have replacement cost, construction matters.

@Larry Alexander location can also matter. For example a home in the country or just outside of the City limits where the fire department is not full time would have higher rates. Homes in the mountains of course with wild fire exposure. Homes where the distance to a fire hydrant is outside of the standard reach of a fire hose (~600 ft last I checked). Homes in high crime area.
Another item to check is deductible. Sometimes agents don't use the same amount for all policies. For example a $10k deductible on $400k of coverage was half of a $2k deductible. Incidentally, $10k is a good chunk of the cost of a new roof (think Colorado hail storms).
In Texas, the age of the roof accounts for about 1/4 of the price of our policies. A basic hailstorm can ruin a 25 year old roof very easily, much more so than a new roof. Age in general leads to more claims (older roof, older pipes, water heater etc.).
Lots of good things already mentioned, but age is the likely #1 factor. Insurance companies don't like things over 20 years old. Replace the plumbing, electrical, roof, and water heaters and you'll probably see the rates drop significantly.
Other factors could be number of corners (the more corners the more expensive to rebuild) or fireplaces or the fact that the house is at the end of a very narrow cul-de-sac and rebuilding would be more difficult.
Cost of purchasing a house is independent of the cost to rebuild it. Have you had a claim since your last other policy renewed? Claims free discount is huge with State Farm.
I'd check your overages and deductibles from policy to policy.
Also are they all written correctly as rental dwelling policies?
If none of the above explain it, I'm guessing your agent got away with something for you on the first couple that he didn't get away with on number three.

One thing I did not see mentioned is to check the coverage. There are different levels of what is covered. Special form is the highest level of what is covered. Lesser coverage is at Named Perils and lowest is Basic coverage. The lower premiums on the other two policies could be partially due to less things covered.
