There are an estimated 1 - 2 million crimes a year stopped by brandishing a gun and fewer than 600 deaths from accidental shootings.Pepper spray is not as effective.

The BP rental estimator tool is pretty good as well and is usually within about a 5-7% margin of error. 

I am getting 3 estimates on the property in the next week but could also do some of the work between my dad and me.

Specifically in SC, though, I would check two things - 1) see if the ATI exemption applies and actually quote the taxes for that particular property on the county tax estimator tool, and 2) get a ballpark quote from your insurance partner on the particular property.

We have yet to have another appraisal completed but I estimate a new evaluation of $350,000.

They provide free estimates and work with your accountant.

Priced too high, rehab estimates too low, and they don't factor in the cost of selling (commissions and closing costs). 

I would run a cost estimate if you haven't. 

Here are the numbers I know so far:Rents4 units all currently occupied on one year leases- #1: 1/1 $995 monthly- #2: 1/1 $995 monthly- #3: 1/1 $995 monthly- #4: 2/1 $1,100 monthly- Gross rents: $4,085 monthlyExpenses- $12,070 taxes annually- $350 monthly insurance (my estimate, they have liability only right now)- $175 monthly landscaping- $120 water (electrical on separate meters, tenant pays)- Total expenses: $1,651 monthlyNOI around $2,434 before vacancy, maintenance, and management (although i would likely self-manage these)Property needs about $50K in other repairs and udpates from what I can see.

I am not going to say there is a best lending model, but brokers legally can not be paid as much as IMB's, and I tend to be cheaper in more situation than not when comparing a loan estimate from an actual lender.
