This is a great way to get your feet wet and one of the few ways you can get into multifamily rentals without 20+% down.Now is a good time to go in and talk to a loan officer at whatever bank you'd prefer to borrow from (a lot of folks will go where they keep their savings/checking).It would also help to have that discussion before you start shopping so you know how much the bank can/will qualify you for.

That includes Realtors or operators.I've wholesaled more than most, it's the best way to get a new borrower into a poorly performing arrangement, it's a cure for pre-foreclosure issues and I've flipped contracts under a variety of circumstances.

They are not even cousins.The IRS isn't in charge of assessing financed transactions except as to tax matters, your CPA probably isn't versed in originating financing agreements, that's a bit out of the domain for a CPA and the Federal Tax Court isn't the proper jurisdiction for RE transactions except as they pertain to taxation.They were also speaking to what not to exceed, not what the customary or average credit was being allowed under options, 10% of "firm" equity places a buyer/borrower over the hump for the financing required, most contracts shoot for 10% equity to be acquired.Dodd Frank incorporates the SAFE Act by specific reference.

I would recommend you find a lender who enjoys working with the investor/self employed borrower or one who invests themselves because those are the ones that can probably be a huge resource to you.

You could get a co-borrower (equity interest) or co-signer (no equity interest) depending on the type of loan.

Did they borrow 180?
