Probably the easiest way if you are going to keep the condo is to have a rental agreement with a tenant written up showing that you have at least neutral cash flow, if not positive from the rental income and then have lender who will count that income.

Right now the rating for Z is "neutral" and Rdfn as "sell".Most of realtors I talk to feel the discount brokerage concept can sacrifices service quality.

Most rentals are debt neutral, meaning that they really don't add to your debt very much if any at all and they may add to your income if you bought them correctly.

Do not get over leveraged so that you need to sell when the market is depressed and historically you will do great.I have also purchased an RE at near cash neutral. 

Therefore I do not have a set minimum on cash flow but we have never purchased a property with negative cash flow projection but we would consider doing so.Here are two examples of properties that we purchased that cash flow was not a primary consideration:A Duplex that penciled out at about cash flow neutral upon purchase using conservative numbers. 

Firstly, the basement walls' color was black / dark gray and we discussed on the phone that they will use some neutral color for it.

The one on the right behind the sink would be my choice but all of them are tasteful and fairly neutral so I don't think you can go wrong

Choose a neutral satin/eggshell paint, wood laminate or vinyl plank/tile flooring, $1,600 for appliances, maybe paint cabinets white or neutral.

If I financed at 25% down and was cash neutral my ROI for the year was 70%. 

With enough value add I would  purchase a property projected at cash neutral.
