I just received the documents from my lender showing total estimated closing costs of $12,400, making the estimated cash to close $38,400.

It needs some updates (~15k), but a comp within sight distance of this property that has been updated is listed for $139,980, so I'm estimating my ARV at $130,000.

I've estimated Gross Rental Income @ 4000, Annual Property Taxes are 2400.

Would go to a house and able to estimate the repairs needed.3.

I really enjoyed this specific agent's tenacity and he was able to always tell me what I needed to hear and give me a very rough estimate of the things that might need to be replaced on all of the walk-throughs we ever did.

In my estimation, your cost to buy and fix such a property is probably not a profitable project. 

@Marichelle Lao based on estimates and work I’ve had locally I feel like that estimate is high.

If you're estimating you will have 30% equity when your done remodeling, you can be off 30% and still be okay.  

I know this varies with a lot of things but I really just need a ballpark to factor into my estimations (e.g. $10k?

A realtor would be able to pull comps and evaluate the house to make a rough estimate of the current value of the house and also what it would sell for fully updated.
