.* Call local property mgr's and/or ask for referrals from your relator friends/associates, and ask them for referrals - sometimes they will be nice enough to offer helpful advice, especially, if you tell them you will consider using them when you turn the house into a rental in a yearAs a 27yr appraiser and Realtor/Broker, the paint job has minimal affect on the value, unless it is so bad that I have to mark it down in quality and/or condition.

What you need to do is hopefully go to the lender's website (that your relative was using to pay the mortgage) and just make payments to the bank. 

There is NO 5% money unless its your relatives lending it to you.. that on its face is showing you they are frauds and fake lenders full stop. 

Your desire to ensure that you are making the right decision and to request additional time to review the property are reasonable steps, especially given your relatively new status in the field.

The issue is that fix and flip and DSCR loans are business purpose loans where you are required to sign an affidavit of business purpose / non-owner occupancy saying neither you nor your relatives will live at the property.

Has your relative been the only tenant?

Can't really use 1031's since your related.13. 

They will stalk you, and your relatives.

@Adrian Thomas- regarding the co signed loan...if your relative has  made  the past  12 months  of payments on this loan and you can  furnush  proof of this - many lenders  will allow you to  remove this  debt from  qualifying ratios 

Also bear in mind that you will only be taking out 75/80% of ARV so make sure that your buying the property at that steep of a discount otherwise you won't be able to take out a loan then what you owe to your relative.
