New construction lending for 2 - 4 units

[Tauren Mills]

I have purchased and renovated a few properties and am now renting them. They are all SFR except one has two houses on a single lot. I've used a combination of private lending and traditional lending based on my personal credit worthiness. None of the properties are currently financed via my LLC.

I've found some bare land that I'm considering acquiring with cash. It is zoned multi-family and will support a duplex. However, the city recently updated their rules to also allow tiny homes. This property could instead have 4 tiny homes of up to 400 sqft. Each of them can also have a loft that isn't included in the square footage. I'm not sure which way to go yet, but if lenders won't work with tiny homes, that is something I need to consider.

I don't know what is involved in getting a construction loan and would like to get a better understanding of how to start and what to expect.

1. How do construction loans work? 
2. Do I start paying the full amount immediately, or do I take draws and only pay on the drawn amount? 
3. Do I have payments during construction, or are they delayed? 
4. Are payments interest only?
5. Once construction is completed, do I then need to take out a different loan?
6. Since this is under 5 units, would it be residential, not commercial?
7. How much of down payment is typical for construction loans?
8. Does the value of the land factor into the equity/down payment calculation?
9. How do I find a lender that does construction loans? Google is not proving very helpful. Any red flags that I need to be watching for? 

Thanks for the help!
