Here's what I recommend:
1) Find a reputable real estate agent or expert in the field. They can provide guidance and help with finding properties that fit your needs. It's important to remember that their commission goes up when they get you into a deal, so it's best not to be too trusting of them.
2) Look at comparable sale prices of other properties in the area; this will give you an idea about how much the property should be worth if there are no major discrepancies between those properties and yours.
3) Do some research on taxes - if there's a major discrepancy in your assessment and what you could find out about market value, this is worth getting into.
4) Remember to look into closing costs and all possible fees that come with buying property (if there are any). Make sure you're clear on every detail before committing to the purchase of a home. If anything seems fishy or unclear, get help; don't rely on the realtor for everything.
