The margin for error is just to slim when you are borrowing at negative leverage.I would love to attend one of @Jeff Greenberg's meet ups and will try to fit it into my schedule. 

One thing I did see on a bigger pockets post was that to calculate maximum purchase price you want to use something like 70% as the margin (ARV *. 7 - Repair = maximum purchase price).

This is abpossibilirt though if there is some margin. 

She explained that one of her investors pulled out, which is why they are short of the $12K, and they do not want to go back to the lender for the extra amount.The margin on the flip is large enough to where she can offer this crazy return.

That’s a good deal anything above 8 good luck your margins will be off and you’ll have to work till the day you die.

but realize that if you're using an FHA loan it's likely a retail property and this will mean lower margins.

You're real estate commission, escrow costs, holding costs (debt service, taxes, insurance utilites) while you are fixing it up and getting it sold will more that chew up any little margin in it.

Those that can't buy now or at the margin will have to buy sometime else that fits their wages or not buy.If wages are part of the driving forces behind a rise in inflation, then consumers and investors will still continue to buy at the limit of their income.

Those options either marginalize the custodian's role or completely eliminate it.For CA residents, there are some additional considerations because of the state's franchise board tax.

Most of the time you cannot enter/ walk around the property.Calculate a max offer based on amount owed on liens, cost of rehab, closing costs, and with a margin for profit.If you get the house and there is a tenant, you must honor the contract (if you are not living in it) up to one year.
