The lack of inventory in many markets is worse than a lot of people are really acknowledging. 

Just for CYA reasons, (if you do not already have it in your Lease) you may want to consider including a clause that states "By signing this Lease Agreement Tenant's acknowledge and agree that they have examined the premises, and all contents therein which convey, and found them to be in clean, good, safe and satisfactory condition at this time (with exceptions noted on Move-in Inspection Sheet)".

It's tough to get read receipts for all email "systems" so I always state that this email serves as your official written notice and ask them to respond acknowledging that they received it.

it is completely legal to make pen and ink changes to an existing contract as long as all parties acknowledge the changes.

When a person goes to look at an as is property that is in disrepair it pretty much goes without saying that there won't be much negotiating on the price because the seller is acknowledging the condition of the property by how low it's priced compared to move in ready homes!

Receipt of the above disclosure is hereby acknowledged.

(acknowledges their concern as valid while downplaying the severity)When I lived in the property I used to do (whatever) to control them.

All are incredibly important things to learn.Problem I see with a lot of the real estate education out there right now is the price is extremely high and what they are selling is a lot of pipe dreams.Thanx much for the acknowledgement.

. - finding the right list, sorting it adequately, sending out the right message and handling the responses as they come in).Learn how to do proper due diligence (figure out all the relevant details about each property, learn how to establish a ballpark value for each parcel and make appropriate offers that will actually allow you to make money in the end).Learn how to list and sell properties (understand where to list them, how to attract the most attention, how to offer a value proposition that buyers actually want, all while acknowledging that some properties will inherently sell a lot faster than others... and this is okay).There's a lot more to be said about the process as a whole - but this is the "10,000 foot high" overview of what you'd need to figure out in order to operate a feasible land investing business. 

A simple professional response acknowledging receipt of your offer, advising of the rejection, showing basic courtesy - would likely have engendered more trust on your end.
