This will cost about $400 to replace in addition to $350 ive already spent earlier this year to keep in going. 

Hey Guys and Ladies! I'm an agent and want to flip my first house.  But.......... how do you get started with no capital?  I probably need someone to invest with me but I don't know where to look for the deep pockets....

If the cash is available then add the ac unit and replace the furnace as well.  

Do nothing before you will estimate how much it will cost to replace this tenant (unite update and time and may be eviction).

You will need engineers to do drainage studies.It will cost you at least $25,000 for the subdivisionYou will have additional costs during development because you will likely lose your water tap and your wastewater connection on at least one of the lots (I'm assuming that the existing connections will no longer fall within the guidelines of the land development code)..The city will tell you that this takes 6 months.

All units are as originally built and nothing has been replaced or improved (including HVAC).

Upstairs there's also some updating that needs to be done, drywall repairs, flooring replaced, etc.  

I work full time as an engineer, so my career has been my main focus up to this point.I purchased my first house in 2004 (and paid top dollar to a flipper).

I also need to replace the pool pump at this particular property as its around the same age and is on its last leg.To fix the compressor (replace the compressor) it was $2,200, to replace the whole AC system is $5,700.  

My husband is an engineer/ programmer and I'm a financial analyst.
