I'm loving the BRRRR method, and I think this is definitely the way to go to minimize risk, start with low to no money down, and grow rapidly.That said, I'm finding it difficult to find out around how much you should put down with private money up-front? 

Now read, ask and learn everything about private- and hard money lending First to prevent your cash from evaporating.

Rick, I tried sending you a private message but the feature is disabled.Is there another platform I can message on?

A couple of my private investors bailed.

I bet you run a seriously amazing, and legit, business.I also have a soft spot for this because I volunteer in California prisons, one day a month and six full weekends a year, and I work with the inmates directly and I know for a fact that so many of them have your kind of mind and drive and skill.

This is the 4th property I have purchased which I know will be a solid investment but it has so many different opportunities I am having a hard time formulating a next step (develop separate lot, focus on renting, convert the building, move on to another property…..).NEAR FUTURE GOALS: I would like to complete a flip in the next 3-6 months with the use of private money from family and possibly hard money.Finally, I would like to say although I am in a state of confusion; BP definitely is helping me assess all the different opportunities that are available.

I tried to contact a few of the HML and private lenders here on BP recommended list and one, in particular, is willing to work with me but I have a few questions that I hope I can get answered.1.

I bet @Jon Holdman has a good answer to this - per usual.

What tightens up the market even further is that more rental grade SFR's than ever are being held by private investors and they are not thinking about selling. 

I bet they change their tune when you ask for this.
