Beginner Question: Lot Space

[Christian Gabriel]

I am an aspiring wholesaler getting in the habit of reviewing properties to get myself into the habit of finding deals. I am in Las Vegas however the property is in Detroit,MI and needs ALOT of work. Has been vacant for over 10 years and I calculated rehab costs @ $30 per sq foot bringing total rehab costs to approx $33,420. I will be reaching out to a real estate agent for comps as I had no luck finding comparable properties that were sold within half a mile within the last year so i can determine the ARV but I am not getting my hopes up as the home is not in the best area either. I am a newbie so I am not sure if I am focused on the wrong things, so I am reaching out for any input with this property. While the house is 1114 sqft, the owner advised that they own the lot space next to the house, which is 4356 sqft, the lot space is really what peaked my interest for more potential but I am not sure how to incorporate extra lot space such as this when looking for a deal.

Thanks!!
