I definitely think that homes are being priced a little higher than they’re worth, but not prohibitively high.For the price your looking at, I’d say jump on anything near Philadelphia street (close to I75).

I don't want to promote on here, as it's prohibited in the rules.

@Andrew Royce, condos are nice, but what do you do if the bylaws get amended to prohibit rentals?

The police and the courts would most likely laugh at them assuming your lease prohibits satellite dishes or modifications without your consent.

FHA prohibits a person from having 2 FHA loans at the same time unless with a few rare exceptions, most notably a divorce where a spouse moves out of a house with an FHA loan and is no longer on the title and has a court-ordered contingent liability.

While this is not a prohibition on getting a new loan it will make it more difficult if the second loan is FHA, and the reason his advice it so spot on is the transaction will go so much better if you start with FHA and do VA second.  

Both of them carry the liability of making sure that you avoid 'prohibited transactions' and dealing with 'disqualified individuals'.

That depends on state law, so it's a state specific issue.One thing they can probably do is fine the homeowner lots of bucks and make it cost prohibitive for the homeowner to rent to Airbnb.Then they can put a lien on the property and when they go to sell it, have fun negotiating with the HOA.

Some don't prohibit it, but enact laws to discourage it with high purchases taxes or restrictions when you sell.   

Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.You don't need the additional expense and administration of an LLC to have checkbook control.There is a built in-Roth component whereas IRAs are either traditional or Roth, not both.A spouse can also participate in the same Solo 401k plan.The Solo 401k has additional tax benefits over an IRA when investing into real estate using leverage.The penalties for prohibited transactions are less severe.
