As a former NYC realtor and local resident, I viewed your listing on Zillow and Trulia. My comments as follows:
1. You need to pay for professional photos. I was shocked that your listing has no inside pictures. Buyers skip listings with no pictures. Why bother to see a house if you can't preview it online? You need at least 10 pictures (kitchen, bathroom, bedroom, living area, dining area, front of house, back of house, separate entrance, laundry, main road in the neighborhood or your street).
2. Your description is WAY too long. It needs to be cut in 1/2. I agree that you need to keep "legal 2 family" in the first sentence and in all caps. The picture of the second entrance will enforce that. However, the rest of the description should be short - distance to nearest subway entrance; distance to nearest bus stop; what subway line is to Manhattan; what do you like about the neighborhood; favorite places to go in the neighborhood; if you had tenants, how much was their rent; if no tenants - do not mention rent amounts; nearest public elementary school; dates of any upgrades or improvements (if none - don't mention anything older than 10 years); etc. Your description does not excite a buyer to move to your neighborhood. Remember, buyers are looking in other locations too.
3. You are way overpriced. Go to Zillow.com and type in Queens County, NY. Use the filters to check: Listing type - For Sale (all); Potential (all), Sold & Pending. Check Houses and uncheck Land, Condos/Coops; Leave price blank - it should say "Min" "Max" in light gray. Wait until everything populates (it will take a while). Use the map on Zillow and zoom in to your neighborhood. This will focus on listings in your area. Now click on "List" and start reading all the listings for sale in your neighborhood. Compare each one to yours. You will see most homes are $700K - 1.5 million. You need to review your price. I think it should be priced at $1.3 million because you have no photos yet.
4. I would advise paying for a home inspection. The issue is buyers who need financing from a lender will be required to pay for a home inspection. As the seller, you don't want any surprises. It's possible your inspection will be fine but the buyer's inspection will have issues. Or it may be the opposite. In any case, it's better to be prepared than to have "Surprise". If your inspector finds issues, you can always fix it. If your buyer finds issues - guess what? Your buyer will have a clause in the Purchase Agreement that says, the buyer can cancel and walk,away. You are back to Square 1 - finding a different buyer. Well, that was a waste of time. You can get lucky and if the buyer really wants to move into your home, you can always negotiate on price.
5. Make sure every buyer sends you a pre approval from a lender or Proof of funds from their financial institution. This needs to be emailed to you BEFORE you show your home to the buyer. No exceptions. You live in a nice area. Ripe for criminal activity. It's NYC. As a former realtor, not all buyers are trustworthy. Many want to see homes to rob them later. Buyers that are pre approved by lenders have given their personal information and had their finances reviewed. Lenders can track them down. You will Google the lender and use the phone number online to verify the pre approval. Pre approval letters can be fake. Do not use the phone number on the letter.
6. Make sure you buddy up for all showings - no exceptions. If you have nobody available, go to St. John's Univ. or Queens College. Students need cash and have flexible hours. Pay about $25. to have students be available for showings.
