Chances are there will be a initial delay in you receiving payment due to government paperwork.

Chances are if you have been informed of a flood risk you are $1500/year or above.  

Since the owner is deceased you chances look good. 

Tenants that pay late should never get a second chance.

Now if you are strictly doing flips then it may be more effective to only knock on doors that are one of the following:Sheriff sale propertiesPre foreclosure 90 day late 2+ year late taxes Code violations Owner occupied evictions (usually multifamily) Expired listings FSBO This is more time consuming and requires route planning but for flips this is the list of people who have a higher chance of having distress & would give up equity to solve that  problem & close quickly. 

What does that conversation/process look like as to increase your chances of converting it into a deal?

it is somewhat common for properties in our area to touch, since they are built over 100 years ago chances are it is an existing easement if it is on your property and there is nothing you can do about it

However, I am concerned that with interest rates on the rise the banks may cancel our lines before I have the chance to find a worthwhile deal.

Is that a typo by chance?

With you being in the middle of it, you stand a good chance of finding some good opportunities.Good luck investing.
