Welcome to limbo -- decent activity level, but no offers. Although offering a seller's assist may be an attractive inducement to a prospective buyer, you should consider either a price reduction or "investing" in your property's appearance in step to set your property apart. At this moment, you are helping to sell your neighbor's home, which may be priced lower and/or in better showing condition. It's a tough market, and differentiation has never been more important.
Everything boils down to price. If you haven't made any upgrades and no one is offering, then you should do the upgrades or drop the price. If your home does not have any curb appeal, you should either get it up to par or drop the price. If you haven't decluttered/depersonalized your home, you should do that too or lower the price. If your home is more costly than the other similar homes in the neighborhood, you should drop the price.
If you really want to sell your home, you should ensure that it's priced properly first. Having incentives also works well. As my colleague said you could offer up to 6% towards closing costs if the lender allows for it. And yes, it can always help for a quicker sale. However, the listing price must be in the same neighborhood as the similar homes in your area.
Let me first answer your question regarding a seller assist - often this comes in the form of a concession on your part to cover all or a portion of the buyer's closing costs. This can be helpful, and sometimes necessary, if you attract an FHA buyer that has only the down payment requirement as available cash, but not additonal funds to close. You can offer to cover, the concession can only be used to cover closing costs so if those costs are less than what you've offered out, then your concession will be for the documented closing costs only.
Remember the Federal tax credit that recently expired - it created demand and urgency among first time buyers. Since its expiry I have seen sellers offer out a similar up to $8,000 concession to try to incent offers.
Here is my recommendatioin - I recommend that you take fresh look at your price. Here is the hard truth - 7 months on the market, lots of activity, no offers = pricing issue. You were on the market when the Federal Tax Credit was in play so your price was tested under the "best" (by current definition) of circumstances. It is a time to reposition your listing - freshen it up, restart the clock and price it right. Price is what draws buyers to property - concessions are generally embedded in the comments. You may have to go there in the end but the best way to get a different result is through a price correction.
