While sophistication of your equity partners (private money lenders) will vary between residential and commercial, the principle of raising private capital is the same.You need to develop your own system which allows a constant stream of PML even when you don't need the funds and/or don't have an active deal under contract.For example; I raise private capital by offering free educational workshops for people with self-directed IRAs.

I will summarise my learnings to date and share a little about the process/rules I have developed here to hopefully be successful in REI in the Portuguese market.

That is smaller units built with higher density to make the numbers work for both buyers and builders.Adapting to these challenges isn’t easy, but it’s necessary to keep up with the market.What are your thoughts on how builders and developers can address affordability and supply issues. 

However, you have to invest in specific communities where they are encouraging development.
