I usually ball park it by taking past 6-12 month sales comps of similar properties sold within a mile of the subject property.   

This new fancy management co dropped the ball and delayed the work 16 business days so it’s been interesting dealing with them.

You also need to check with the utility companies and get cost estimates from them for availability, fees, hookup charges, transformer and power line/power pole locations or relocation requirements, water, sewer,gas, cable etcYou will need ball park cost estimates from site work contractors for site work, roads, installation of utility lines etc.

The experience should have been a good one; yet they’ve dropped the ball but you already know this. 

I wish I did when I was 21 or my 22yo heard anything I said about this kind of stuff.As far as suggestions.....you can get a secured card pretty easily that you can use and pay off every month to get the ball rolling.

@Lawrence Chun my low ball offer was declined by the seller.

We’re looking for contractors to get the ball rolling with quotes and building estimates.

@Mengzhu Rolff I'd recommend first underwriting the property to get a ball park value at the time of acquisition then run the numbers in it's current state.When it comes to commercial properties, lenders determine value based on stability and P&L's, you have to prove to them the new value through increased income

That should give you a ball park figure.An example: let's say NOI is $50,000 per year (remember, this is BEFORE debt service) and CAP rate 7

I assume that the first purchase pretty much gets the ball rolling and hopefully paves the way for your second, third, fourth etc.?
