My comments may be influenced by my local RE market, which may be different from yours, and my buying experience was during a somewhat 'hotter' market, where good, well priced properties don't sit very long. Properties do seem to sit a little longer now, even in my area.
That said.. based on the pictures it looks like a decent, turnkey property. That it's been sitting so long suggests price is too high, or there is some other a complicating factor.
But.. a look at
movoto and
redfin says the property is pending & contingent. Is that you, or did someone else get in before you?
Either way, for this or the next property..
In terms of due dilligence, my main advice is to get a good home inspection. Check the attic. Check the crawlspace. Check everything. But it's not just the inspection. You want to know all you can find out about the property. Read the HOA CC&R's. Find out about any additions, repairs, permits, etc.
I personally didn't care too much about how much earnest money was put down. We made an offer because we're serious and not planning to walk away. For one property, we put the maximum earnest money we could and ended up walking away because of issues with the property, and got all our money back.
For price, get good comparables and determine for yourself (not just from your agent) what those comparables say the property is worth. Realize that it's not always a straight up $/sqft either. For example, significantly larger houses tend to have lower $/sqft, so do
singlemulti-level homes. Your best bet is finding comparable properties that are as much like your property as possible, in terms of size, characteristics, location, etc. Then ask yourself what it's worth to you. You don't want to overpay, whether it's relative to what the market say, or whether it's relative to how you value the property.
