So what if the heloc amount is enough to cover 20% down on investment property and cover renovations.

By keeping them MORE than 2 years, I better the amount of vacancy I budget for.

From a $ perspective you get the same amount of appreciation, depreciation, loan pay down, but here you have cashflow and if if a tenant moves out, you are only 50% vacant instead of 100% vacant.- Generally the same logic applies as above.  

More importantly the amount of communication and follow up necessary on site.

Confirm the amounts are consistent (there's that word again!).

:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

As for your neighbors, they could have exemptions like Homestead, widow, military disability and many others that can reduce the amount of taxes.

It likely means you have that amount of coverage when caused by another peril and as mentioned it's typically a significantly lower limit than other coverage amounts.If a pipe bursts, it will likely be covered. 

Unless of course they were using a SEC vehicle that allowed a certain amount of non accredited. 

if yes then you got the answer, an appraiser will never come in with the proper value of A turnkey, because they rely on local comps even though those comps need much work and the principal is already done and cash flowing.2- These turnkey sellers usually purchase there properties for far below market value, if this is the case the appraiser might appraise for A lower amount due to the previous sale on the property.I don't know what turnkey seller specifically you are talking about of, but if their customers are happy then you got your answer, if their customers claim they were ripped of then you got the answer as well.
