Nick,
I have been following this
thread for a while but held back on commenting. I have to ask a couple of questions first though. First, are you planning a cash-up-front deal for the deed to the land? This is tempting, but I would really want to see the deed first.
Secondly, are you using a realtor or a real estate lawyer? This costs money, but they are experts in finding just these type of issues in land transactions. When I bought my property I had to do so with 2 easements. This is OK, but I am glad that I knew about them in advance. If you are unsure about the legalities of the purchase and are not an expert in real estate yourself, I would highly recommend hiring someone who is an expert.
Third, you will want to know what the taxes are that you will pay once you own the parcel of land. They will almost certainly be higher than what the current owner pays.
Last, a brief anecdote. I know a person who thought he found the PERFECT plot of land and bought it in cash he thought he had (long story here). But what he did not know was that the place he planned to build (just about the only buildable spot on the whole, highly sloping plot) was on an easement for the power company. He now owns a piece of land that is practically unbuildable, and even if he were to build in an almost buildable spot, he would have to shell out a LOT of money to get a foundation that would be sturdy on a very steep slope.
Long story short, I would want to be VERY certain of the legal details before I bought or you might end up up owning something that you did not want or did not know you had on the property.
If you go through a bank, they will require full legal documentation. Conceivably you could go through a bank to borrow the money (or just some of the money) and pay it right back immediately so as to not incur loads of interest. And right now interest is at rock bottom rates. I totally understand wanting to side-step the bank, but maybe you could make the bank work for you rather than you work for it.
I guess the bottom line for me would be that I would want to be fully informed before buying.
I wish you the best of luck. There has been a lot of very good information already made on this thread, but in my limited experience of real estate transactions (a total of 3) caution is warranted as when you buy the property, you buy everything attached to it such as easements or liens against the property. Again, I wish you the very best, I just want the transaction to work out the very best for you.
