There are some realtors that are more investor friendly than others for sure, but one thing to keep in mind is that a realtor makes their money as a percentage of purchase price, so just speaking logically they're not going to be the one that's getting you the absolute rock bottom price.

Unit availability- What percentage of units are available day 1 to rent?

Most of our Section 8 tenants pay a portion of their rent and that portion can not exceed a certain percentage of their income.

Plus, if his idea of investing in RE is buying a home and hoping to bank on a certain percentage of appreciation, then he's probably doing it wrong.I think it depends on your situation, your level of involvement with your investments, your tolerance for risk, and a thousand other factors.

HUD requires the Section 8 tenant to pay 30% of their income toward rent; if income is low enough, this will be far less than the percentages in that quote.

One would be to do it as a loan and just pay a fixed percentage. 

This property meets my criteria which is that NOI/(price+repairs) is 3 percentage points above my cost of money.Good LuckBill

If your question was more about flipping, the percentage of ARV, then it's just that in order to make a profit you have to buy at a low enough price to afford to do the rehab , pay the holding and selling costs, and have enough left over to make it worthwhile.

My properties always seem to get more than the Zillow estimates but I can use a percentage increase above the Zillow estimate to figure out what to ask for.

Your best bet is likely to be a hard money loan...in which case they would lend a percentage based of the value and repairs of the house, and you would need to come up with the other part of this...which I think most hard money lenders would be ok with that cash coming from your parents.
