Finding contractors in Queens NY

[Faysal Alam]

So I need a whole bunch of work done to my soon to be house hack , the list is as such but not limited to in order of priority :

-Roof for house and garage

- siding

- all windows and window frames

- kitchen and bathroom reno in 2nd unit

- fix minor foundation cracks

- upgrading all electrical outlets in 2nd unit

- gas fired boiler will need to be replaced but can last maybe another year or two without replacing if serviced

- water heater will need be to be replaced soon

- appliances for 2nd unit

- leveling the hallway of the 2nd unit

- painting the foundation and the 2nd unit

- both units currently have a styrofoam ceiling which makes the units look smaller than they are , but this will only be if I have enough money left over .

The first unit is in good shape .

Also want to do a cheap kitchen renovation in the basement if I have any money left over

What should I estimate for this project ? How should I go about finding contractors for all these jobs ? Should I have one person for everything or different people for different jobs ? Contractor referrals would be appreciated . The house is a duplex with 1814 SQ ft .

Also what other upgrades if any would help build equity in the house ? I'm buying for 715k but it appraised for 745k as is . Looking to put in the work and have it appraise for around 850k .
