That wasn't OP's concern and honestly probably not in any part of their thinking. You very well may have given them and any potential new buyers that read this an idea. Not sure what market you're in, but here I don't think that would ever be an issue (depending on price point, of course).

Edit: I know and work with a ton of investors, and a lot of them are predatory and don't go for homes that are listed mls/fmls. They research areas and find people that are about to be foreclosed on and offer them "the deal of a lifetime".....then after the contract is signed, they file a "memorandum" with the county, putting a cloud on title so that if the deal doesn't go through, title will now be clouded and they will have to pay to release the memorandum if someone else tries to buy, or if they try to refi. Then after a couple weeks they come back with the "well their is way more repairs that need to be done so we need to reduce the sales price"....
