Construction is mainly CMU, Concrete, and Steel (at least for my projects), and there is a bottle neck of those resources as only few supply the area.

The main advice I would recommend is to begin networking.

I currently live in Southern Maine and am looking to construct some kind of new project rather getting into rehabbing existing residentialProposed Land Budget 100-200kConstruction Budget: 400kAll in 500-600k.I have found that if I do the site work myself including clearing, septic and digging the foundation is that i can sub contract out either steel or a Lester style building (50x150) for around 300k installed with insulation and power , divided into three 2500 square foot units. 

I think the best thing would be to knock out the line of credit mainly because I’ve been putting a lot of time into getting my business up and running, BUT if I could knock out the renovating before March that would be a HUGE win.

Mainly because they advertise saying they have been investing over the last 15 years and been wildly successful.

Of course, IRR matters too, but you get a better IRR when you leverage as well, so that doesn't strengthen the all cash argument.My main point, if one is to be taken, is that an all cash investor should really look at their expected ROI.

Today's Americans want to live on Sunset Strip and pay Main Street USA prices.

That being said the main issue with leverage is being over leveraged.

Miami/ Coral Gables, even worse. 1500 1700 brick houses without a garage on main roads (Byrd ave for example) 1.5 MILL is just nuts.

I invest locally and invest out of state, and the main issue for most is the shiny diamond syndrome providing you the reasons why investing (insert area here) is the best place.
