Some towns use a per square foot construction dollar amount.  

Best is to start with a performing note to get your feet wet, then try a NPL, though be prepared to spend $4-10k  to get it paying or foreclose.

Obviously if the subject property is on the water you want to use as many comps as possible that are also on the water, this isn't always possible because there aren't always a ton of waterfront homes that have sold in many markets so you may have to use both, but it is a lot easier to adjust for square footage or bedrooms than it is for a waterfront property. 

Assume ($150,000) in rock roads/parking, electric, security system and fences.  150 is really light, we have 100 on a square 2 acres. 

How much of an issue is it that tenants have to duck their head down to 5 feet entering the stairway? 

You don't want to waste anyone's time without getting that squared away

Wow, how large is the house : 100,000 square feet?

First property and wanted to get my feet wet.

I want to get my feet wet before I put a lot of money in.

With Biden potentially cancelling student debt next year, I am finally ready to seriously begin dipping my feet in investing.
