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

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.

They provide free estimates and work with your accountant.

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

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.

Hey everyone,I’m new to REI and I’m wondering if you guys have any advice to share on coming up with rehab estimates when you’re just starting out, and don’t have a long track record to go off of?

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.

It's oversaturated with crappy wholesalers who don't know ARV and can't estimate repairs costs.
