Hire a contractor or GC with clear terms for execution and completion.Secure financing early, whether through cash, private lenders, or hard money loans, ensuring reserves are included for unexpected expenses.

Anywhere from $500 - $2500+ depending on the insert you install and whether you run the vent and exhaust up the old flu or cap the flu and vent/exhaust through the side of the house/chimney.If you hire out the entire job, expect to be in the $1K - $1200 range.

A good ballpark is $1,000–$2,500 per unit, but this depends heavily on how extensive the turnover is and whether you’re self-managing or hiring contractors.If you’re looking for more precision, connecting with local property managers or contractors can provide insight into typical costs for properties like yours in the area.

Many times though the investor acts as the GC and hires all the subcontractors.

That said, hiring lawyers to write contracts, background and credit checks on strangers that already look nefarious may just add to the stress that we're trying to get rid of.

Perhaps a nice 1950's built bungalow.Always hire a 3rd party property inspector to give you an unbiased feel for the home.

@Jae Yoo you should read your PM contract very thoroughly or even hire an attorney to do so, before thinking you can just break it.How would you feel if a tenant just broke their lease with you?

But this comes with additional requirements you must achieve (look up REPS). 

If your landlord wants more rooms painted, I would tell him to hire a contractor and I pay 3200.You can roll two rooms in an afternoon and in the end it's only $100 and at least you have someone who seems somewhat flexible.

It’s worth a look see, just do your homework up front before hiring the other professionals to make this happen.Good luck
