Ask him for a survey or anything he knows about what is allowed on the land and what variances are required.  

I've noticed that lots of wholesalers (not so much on Biggerpockets) have this tendency to ask questions like they are filling out a survey.

You need to analyze this property from top to bottom, you need to do a rental survey for the area to determine ARV.  

I would dispute every  fee that was not originally disclosed at the old sales price except for  the survey fee, which is valid.  

You would need about 12k to 15k for all closing costs typically (legal, survey, cost reserve stable, phase 1, site inspection, appraisal, etc.)If the bank allowed a seller carryback of 10 to 15% you could go higher in price and leverage.A 60 unit at 500 a month rent for 2 million for example would look like this.500 x 60 = 30,000 a month x 12 = 360,000 yearly divided by 50% costs = 180,000 NOI (net operating income).

You need to start with a markey survey and look at the need for storage, what kind of storage?

Developers do a lot more of the heavy lifting or project management like surveying, civil engineering, architecture, etc to get the property entitled.

You will most likely need a land survey done and stamped with application along with local posting and approval from abuttersIts a long process can take months Best of luck

From when to go for financing to when a survey is done.

To get into that path of progress, you are going to have to get a feel to see what areas are set for improvement by talking to locals, surveying the landscape and trends, contemplating potential new transit lines or nearby large developments, etc...
