---You can try to increase your chances of cashflow by buying a beatup property and BRRRing it.2) Buy Class C cautiously.

However I have a contractor who I’m considering partnering with who wants to buy and flip homes in Baltimore.

Quote from @Martin Jones: Hello, I'm young individual who is interested in long term buy and hold multifamily real estate.

It is much more difficult to sell an entire portfolio that has become uninsurable (which would require a cash only sale) or that insurance rates are so high that no one wants to buy. 

If you can solve their problem, you can usually buy the house.When you are a new wholesaler, the best thing you can do is to get some reps calling and looking for another wholesaler in the area, before you put your own money down on it.

Like I said I have the buyer ready to buy. 

There is another house about two blocks over that I have the opportunity to buy off market under market value.

Suggesting to them buying their house for a wholesale range offer or lower dependent on the extent of the rehab, then having a contract in place that gives them a percentage of the profit to help get them back on their feet, paying off debts etc.

Not if you buy 10 at just the right time to hit their sales target.

Yes you can buy stuff over the counter however as said most of it will be junk.
