Contact 2 or 3 to interview them personally then make your choice.TD Ameritrade and Fidelity do not offer truly "self-directed" IRA, they might offer some control, but only within confines of their allowed investments, which is confined to the stock market and does not include alternative investments such as private lending. 

Bank Alternate Stated loans (these lenders are not banks and borrowers do not need to submit tax returns to qualify for these types of loans).

I recently learned about the BRRRR method as an alternative to just getting traditional, conventional mortgages on rental properties, since I heard that there's a limit of something like 4-10 mortgages you can have taken out in your name at a time.

I had posted this in the new member introductions forum but I wasn't sure where it should go so I'm posing here in the starting out forum as well.I've had this idea in my head for a couple years now about buying property and then renting all or part of it out in order to develop an alternative income stream and I just found out about the bigger pockets community a couple of months ago.

Alternatives?

., (b) the type that allows alternatives but doesn't give you direct control over your money, and (c) Checkbook 401k that gives you total control and flexibility to invest in real estate, private lending, etc. 

Your other option is some of the Alternative Non-QM lending programs that are out there, there are several that take the Rent Debt Coverage Ratio to determine the income or debt ratio instead of the borrowers personal income, most of these only have a 6 month ownership seasoning to use existing value, one company that has this program is Impac Mortgage, they have their credit matrix online to view at "http://impacmortgage.com/media/forms/iQM-Investor-...

I have good credit (730) but only about 10-15% down so I am looking for alternative financing but I have no idea where to start.

I am prepping for my first investment and I am curious to hear from folks who have used alternate or non-traditional capital.

By helping them try to keep their house, should they find they have no alternative but to sell, then maybe your relationship is good enough to be in line to work with them.
