For example, what is the monthly revenue for the property and what are the "All In" expenses, including mortgage, taxes, insurance, utilities, repairs, etc...

The Property Manager usually does light cleaning and repairs between tenants.Recommendations or another way to think about this? 

Mainly the panel is in the basement and it would require a ton of work and paying for labor hours + repairs. 

I believe it's because the property is being sold "as-is," and they are unwilling to make repairs or negotiate based on findings.

They pay rent before the due date, clean the property after every client, and if something breaks they usually repair it before I'm aware because their clients will give them bad ratings.

@Gene PanicciaManagement fees vary, but it's not uncommon for a PM to charge fees for managing tenant-paid utilities or coordinating repairs.

If you’re paying off more than $1,500/mo I’d probably keep it barring any major upcoming capex. (3-5 years out so buyer wouldn’t automatically ask for it to be repaired at sale.)Good luck either way. 

That, more than anything will help you answer the question "how much do I need to estimate for repairs"? 

They'd be much better off being a Hard Money Lender and make 5 times that (and every repair to their "investment house" is paid by them...So, if you put $10k down on a property and make $150/month net cash flow your Coc Return (annualized) is 18% which is Very Good.If you followed that and understand it then keep looking for a deal.

You can save a lot on costs if you do many repairs yourself.Look into hard money lenders or private lenders for the initial purchase and rehab.Connect with wholesalers, agents specializing in investment properties, and other BRRRR investors to find deals and learn more.
