People they have existing relationships with and that trust them and want to support this new venture.I am going to disagree with Corby a bit.

We have had stable appreciation in Milwaukee for the last 10+ years, but the issue is that new construction homes have is that they are priced almost double of existing homes in most existing neighborhoods.

The existing homes are too small and would require a large expansion, at which point it would just be better to build new. 

When analyzing a new build/“build to rent” property as a rental, what percentages/amounts are others using for:-Maintenance/Repairs-Vacancy-CapexI’d assume it’s less than than existing homes, but by half or is it safer to use the standard percentages?

Also, if you have anything in your existing escrow account, you will get that back within a few weeks of closing.

No I haven't committed to anything in OR as yet.

Before making any decisions or committing to anything, reach out for referrals and do some research on the company and the offer they are making.

You'll find a ton of kind, supportive, and helpful people here.Are your existing 7 properties currently in Chicago? 

If existing houses are cheap relative to land and constructions costs, and supply is high, it may not be worth developing even if the agency says "do whatever you want".

They need to do all their due diligence including understanding the value that will be added by the ADU, the finance options available, the consequences of adding the ADU (rent control, property taxes, rental limitations, etc), etc.Good luck As with all things, it depends on the investor and the equity.If they are able to leverage existing equity to buy it under a HEL or HELOC, then they are adding equity with no out of pocket expenses, and adding immediate and longterm cashflow to existing stock.We like ADU's because there isn't more land being created in our city that is landlocked...but there is more density available to those with large lot under-utilized sfh.In my market, it typically costs $2 to add less than $1 of value on single build ADUs.
