Putting some things off until later in the project hoping that they will work out. 

I understand that most banks like to use this formula: (Value of home - amount owed) .8I have enough equity in the home to where 80% of the difference in value minus balance is sufficient to fund my construction project. 

As a newbie, this would not what I want to tackle.

There is no way living in Los Angeles with a wife and 2 young kids that I can reasonably afford a loan using a 50% DTI, unless I project my income to rise sharply going forward (which I will not bank on).  

I always try to borrow 100% of the capital for my projects however, that doesn't mean my mortgage is 100% of the ARV. 

Does this builder even have any relevant references for a project of this size?

Wholesaling is one thing I would like to tackle, but BRRRR is a strategy I really want to get into. 

Numbers like occupancy rates, loan defaults, etc. all remain quite favorable when compared to those of SFHs during a recession.On top of that, if you work with a good syndicator, they'll only bring you deals that will perform (albeit not to projections) in a down market.

We are experienced and located in Southern California, so we could remotely manage the project and come up every few weeks.Referrals to experienced general contractors & subs in the area would be greatly appreciated!
