Fence is entirely within my property per a survey that I did.In 2023, I did some landscaping work and replaced the front part of the side fence (and paid 100% for the replacement).

Detroit's population is actually growing according to recent surveys not shrinking Census Bureau estimates: Detroit population rises after decades of decline, South dominates growth (michiganpublic.org)2. 

Plenty of times $ are not in the contract...so when you agree with the seller for sale of $300,000, they think that is what they are netting, when there could be charges of title insurance, surveys, lender required repairs, prorated taxes, escrow fees, etc. 

We'll consider both, usually a midterm rental would have history of rent, however you mention it doesn't, so we'd use an appraisers market rent survey. 

Because it is LOL, I have taken many surveys, Its always the # 1 issue. let me add, and execution.

Clearing, ordering surveys, soil tests.

The best route is using licensed foundation companies and engineers to conduct work surveys to determine what needs to be done and then having that work done by licensed companies with warranties.

If you buy a polluted property, it's highly likely that the cost of cleanup is yours.I've represented a few gas stations in Massachusetts, so from experience I can tell you that you'll need a current environmental survey. 

At minimum, look at the assessor's site on the lot lines but ideally, have it surveyed so you know what you will own (esp if you are going to build a fence or structure).Tons of lessons, always learning, looking forward to reading what others want to share here!
