For a 30 year Conventional loan, I'm at 6.5% rate (6.808% APR) for a duplex, 95% LTV, 780+ FICO, owner occupant.And I'm assuming they're paying $2k of your closing costs - not your down payment.

When you contribute to a Solo 401(k) as an employee, those contributions are made on a pre-tax basis, which means they are deducted from your gross wages before FICA taxes are calculated.

This is insane that these guys got that large of deposits on a pre sale rental house construction sent directly to them. 

The only place I at all worry about from a rental standpoint is city proper just because it got a little overbuilt and there are tons of condos that can’t sell & will be turned into rental’s but that’s mostly a pre-existing condition, though I suppose layoffs could make that situation worse.

Quote from @Jason Hatfield: @Jaycee Greene  they require a non refundable deposit and give 48hrs to see proof of funds I would suggest developing a relationship with an HML/PML that would give you a "guidance line" that would basically be a "pre-approval" for situations like this to present to the buyer/auction company.

While I know Brandon and his team has experience, the going in cap rate is very low for MHP (I was told mid single digit).

Do you have a pre-approval or proof of funds ready?

Specifically, I am looking at partnering with an individual who owns securities (stock and mutual funds) having them take out a line of credit against their portfolio (SBLOC) at a low interest rate, and using that to purchase properties rather than using a mortgage.

@Robert D.Sounds like you need to speak with a family law attorney about separate versus community property rules, as well as possible creation of a pre-nuptial or post-nuptial type agreement.
