How much can your net worth fluctuate daily or even weekly unless you have a huge spike or drop in income/expenses? 

., upload them to CL, put a ridiculously low price, and watch the phone ring.

Come the first week of May and a week in October for the prettiest months and for the sake of rental income.

I currently make a large portion of my under the table and is not verifiable income.

Ultimately would like to create passive income but think a flip may be the best way for us to get into the market.

This means I likely won't be buying a killer deal, but I will still be paying a low-ish mortgage.

Mortgage on $375K based on 4% for 30 years is $1,790Total Yearly Expense is $29,410 and Monthly expense + Mortgage is $4,241The property is giving income of $5200 a month from all 4 apartments, with monthly Cash flow of under $1,000 a month.Even that Cash flow look very good, the Cap Rate is only 6.28% and COC of 7.67%.Also owner is offering to "hold mortgage for balance" - what does that means?

I work full time and plan to continue to do so but would like to add additional streams of "passive" income. 

I look for the basics(tools, transportation, professionalism, working weekends, being on call, previous income etc)3.

* which areas in Tampa offer stable rental income?
