She declares bankruptcy/pays off those cards with the cashed from the sale and moves forward investing as a business entity.additionally, her personal residence is income producing as well since she rents out two rooms on Airbnb and runs her cleaning business out of an office there. my questions are1.

Great income producing property, and will be more cash flow positive if rates go down and I can refinance.

Payroll paid weekly, utilities monthly, meat/produce 3 day. 

Is the cost to produce a median home any less?

My clients there have done a really excellent job of producing cash-flowing properties, and there is a lot of growth in that area.

I know people are comfortable with losing money in the short term until rents and appreciation catch up, but as this is my first property, I don't necessarily want to buy something that produces neg cash flow.

There are some missing pieces of data needed to make an in depth analysis from where we sit and give you more sound advice, however I own/manage property in Tampa which is a highly producing market and:- With $300k to play with you can acquire a $1M property or more which does provide the best cash flow- On a $1M acquisition and $200k (or less down possible) you can achieve 10-30% CoC returns, likely 15% inclusive of management is possible.- Do not forget about appreciation, which is where the real wealth comes from. 

There are classes of income/dividend producing securities (i.e. 10%+ yields) that are doing really well, so extremely passive and extremely liquid. 

I have a business where I design products and have them mass produced in China.

A great cash flow, income producing property.
