And, would that invalidate the contract? Or

It’s also worth connecting with a property manager and contractor early, even if you don’t need them right away.

I studied RE development and investment for my MBA, I am the building inspector for the town where I live and I worked as a contractor before switching to only working on my own deals.

Hire an HVAC contractor to go check it out, of course. 

Especially when the insurance paid for it, contractors don't cut corners.We have probably several water issues every year across the portfolio.

my condolences on your recent lost.there are a few ways you can do this, as mentioned above you can take a heloc on your primary residence which will give you a second mortgage, first mortgage payment wont be impacted. you can do cash out refinance which will give you one mortgage and payment. it will pay the old mortgage and give you money in your pocket to pay for the rehab.or you can do a renovation refinance which is similar to cash out refinance but we would contractor involved  as part of the refinancing and they are paid through the loan

Buying site unseen is a huge risk unless the buyer and wholesaler have a history doing deals together.My buyers trust the deals that I bring them, but I also provide them with in-depth inspection reports along with photos/videos of the inspection along with multiple cost to completes through multiple contractors.

One of the biggest factors in successful flips is building a strong team: contractors, agents, lenders, and property managers. 

I haven’t done my first deal yet, but through hiring a local contractor to build my personal residence I had this idea that I don’t hear people talking about.
