The property needs about 10k in repairs in the property.

That's their job...not yours.Now, if you had that extra $36k to invest in a different property, maybe one just like this one, you would be much further ahead.

After finding a potential property to wholesale, part of the process is to estimate repair costs.

The Judge questioned the repair bill. 

In my head I saw $10k-15k in repairs just on that wall and that took my my max bid to $8k.

Long story short I have a potential deal for my IRA that I am looking at.Here are the figures: Area: North Phoenix (North of Phoenix Mountains Preserve)Condo, 2 beds, 2 baths at 1134 SFSale price is $112,000Downpayment is 10%P&I is about $510, Other expenses (Vac, Cap ex, Repairs, HOA, PM, Ins, Tax) is $583 for a total of $1093. 

Anyway, I decided to go ahead and study for my MD Real Estate License.  

Given the high repairing cost, do you think it it is worth to upgrade all the house to this type of valves?     

And of course your area may be different in terms of cost and also some jobs don't require a full cosmetic renovation, but most of mine have.Then of course check the big ticket items like HVAC, roof, exterior siding/masonry repair, windows, interior sheetrock replacement, foundation and water heater and know approximately what it will cost to fix/replace each if warranted.  

I think the current tenant is paying close to half what the current market rent is and I need to make some repairs.
