My former residence (a condo) has the following monthly financials:$55.00 Tax - County (until Jan 1, 2018, then $133)$39.58 Insurance$74.32 PMI3.375% APRGreenville, SC 29615I purchased it for $82,500 in Oct 2012.

I have a standard 4-page contract that we'd both signed and notarized. 

COMMITMENT: Within 20 days after the Title Company receives a copy of this contract, Seller shall furnish to Buyer a commitment for title insurance (Commitment) and, at Buyer's expense, legible copies of restrictive covenants and documents evidencing exceptions in the Commitment (Exception Documents) other than the standard printed exceptions.

If you go with a submetering contract there is a standard 3 year contract, but you can also get out of the contract earlier with a buy-out fee of $1,500 during year one, $1,000 during year two, and $500 during year three.   

@Matthew Paul - standard emotional roller coaster, right?

That’ll satisfy the 25% down payment but you’ll have closing costs, escrow account deposits, first year’s insurance premium, utility deposits, $ for needed upfront capX plus reserves.

I'm researching insurance policies for my 1st SFH rehab. 

If they didn't I wouldn't even mention it..They should contact their Car Insurance or Home Rental Insurance if they want car repair, you should not be responsible..

Add on insurance ($130 according to Realtor.com) and property taxes ($340/month per this online calculator) and you're at $3,105. 

Lawyer fee is relatively standard, unless a lawyer owns, or works for the HML.
