wholesale deal comps dont add up

[Dameon Pearson]

hello BP I was driving for dollars and came across this house that was boarded up so I looked it up and the owner was living out of town so I direct mailed him and he called and said he wants to sell all of the land ( 5 acres) with the 2,788 house he gave me the price for the land but my comps wont add up because the land is in the millions but the house ARV is only $273,000 what do I do BP should I only negotiate for the house or all together thanks for your help
