Some tools that might help at this stage include AirDNA, Rabbu, Airbitcs and or STR Insights. 

Lastly, if you still decide syndications are appealing, get educated on how to vet the lead sponsor (including deep background checks), the market, and the deal itself (even though some concepts are similar, it is not the same as the single family long term rental analysis).

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. 

Pros include securing the desired property and strategic planning, while cons involve higher costs, financing challenges, and complexity.

This is because the main house often includes value drivers that ADUs do not, such as larger living spaces and more comprehensive amenities.

Quote from @Jerem Kaawaloa: I have spent the past 20 years working in health care and have only ever purchased properties for my own use, including a home and office.

The contract must contain:the contractor’s name, address and telephone numberthe approximate start and completion date, including any contingencies that would change the completion datea description of the work to be performed and the materials to be provided to the consumer, including make; model number or any other identifying information; and the agreed-upon price for the work and materialsa notice advising you that you have three business days to cancel the contract, unless during an emergency you waive the right in writinga notice that all payments received by the contractor prior to completion of the contract work must be deposited in an escrow account

Including one that prevents a unit from being rented for less than 6 days.
