The truth is, they will keep playing games and milk you for every penny they can, then they will leave the house a mess and cost more with cleaning, repairs, and vacancy.

I looking to take action Can anyone help with some questions I haveWill this property cost me to much down the road?

Typically, we see anywhere from $600 to over $1000 per unit (maintenance and turn costs)  depending on these factors. 

Its definitely a big cost/premium risk allocation discussion

There isn't enough information in here about the current state of the house to be able to advise you, but I would think #3 is a definite no as it seems unnecessary from a cost perspective although that market has scale to accept it.

You are still going to have holding costs and a heloc will just have less holding costs that you would if you were doing a personal line or hard money. 

LTRs with long term conventional financing and standard management aren't really cash flowing anywhere right now. sure, there are lower cost markets that look better on paper, but there are costs associated with those supposedly cheap markets as well - deferred maintenance, more challenging tenant base, higher cost turnovers as a percentage of the rent.2. i wouldn't pick a random market thousands of miles away based solely on statistics or numbers. 

But again, your profit after selling costs (and any capex improvements) would have to be in excess of $60ok to really make sense.

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

Real numbers- purchase 907k,rehab , closing costs, soft costs, 840k, all in 1.747 mil, basis for each unit should be roughly 291kappraisal of each unit minimum 400k , so 2.4 mil if for all 6.I might refi only 4 out of 6, that will cover initial loan amount.
