I don't think I'd consider any of that to be perfectly fine, you can check your survey that you may have gotten with your purchase to see if it is on your property, if it is I'd see if the neighbor is willing to split the cost with you. 

The seller and his attorney recently paid for a survey to be done and also paid someone to spend a lot of time at the city to persuade them.

At the link below, there is a survey from University Presidents.

I surveyed a variety of owners and property managers in NH and of the 1,605 units that I received data for, 1,308 of those paid rent in full by April 6th. 

Based on my own survey, most renters own the more common side-by-side(if they own any at all).

After surveying rental prices in the area, it is time to increase the rent to keep up with the current market value.

I spent the money to have the lot surveyed and hired an architect.

@Antonio DeFlorioI've also seen:Buyer to pay for survey and provide a sealed copy to seller.Buyer agrees that their attorney has reviewed the contract and accepts all terms.All contingencies waived.Should seller decide to appeal previous year's property taxes, buyer is to pay their pro-rata share of the legal expenses to do so.Like you said - buyer pays all closing costsAnd all of these things are always buried in the middle of 16 pages.

It is broken down by component costs taken from a survey of real world data and adjusted for time, location, etc..

Otherwise, Swanny has nothing to sell, and after surveying what others charge for multifamily syndications in terms of acquisition fees, asset management fees and mentoring I came out with a steal.
