You should determine your selling price and start advertising the property NOW.

I recommend setting up keyword alerts for each area as they are discussed in the forums daily with advertisements posted in the BiggerPockets marketplace hourly.One thing to note when looking at the individual markets, you can make or lose money in any market.

Currently I advertise vacancies on Zillow; Trulia and Craigslist.

I think the duplexes would be better in terms of phasing the construction with the bank, and I know in my city anything over 4 units needs to meet all the efficiency and environmental guide lines, which drives the cost of materials.

Another way is to find where people are advertising their rooms for rent, and see what they are getting in their areas.

I had too keep our team on track as well as keep up with other trades, keep my company up to date on everything from timelines too materials too meetings etc.

For your first project, use a General Contractor, who has their own subs and who will deal with all that minutia for you, then follow them around, ask lots of questions and learn.Whatever you do, have a rock-solid contract that specifies money for performance and have them deal with materials and the haul-away and bid the job including both labor and materials broken out. 

Because with that one the contract owner is sending it to a super secret list of 100 people vs across the world with mass advertising. 

We have VAs that will actually will advertise the properties in addition to the PM to keep the turnover at a minimum.

Then you have labor, fire-rated misc. materials, etc.
