I can understand Zero offers, but no showings would cause me to be taking a hard look at the properties local competition and see what the disconnect is.

Great success.Life saver cause it was during the lockdown.

This place is also missing a lot of other basics like salt and pepper, sugar, soap, shampoo and conditioner, etc. but the plunger is the one thing that really caused problems.

I had places with not a lot of cash flow that over a couple of years were better cause of increases in rent. 

It is not the interest rate that will usually kill the deal (quotes between 10-14%) as you mentioned this is a way for you to short term finance the deal, but its points you will pay on entry and exit of this short term loan product that will cause things to get VERY costly. 

Also make sure to tell your insurance provider about any other damage that was caused as a result of the leak (flooring, baseboard, drywall, paint, etc).I've only filed 1 claim and it was on a roof, the cost to replace was around $10k.

That's what causes analysis paralysis.

I ask cause I notice I get fixated on such things, but realize it's not worth it always.

7 months is way too long cause you started it when everything was selling, I think you spend way too much for renovation, unless there was no roof in the house and you had to replace many joists.Market was crazy and many houses sold in the same week where I would not even go pass 5pm.You are too late on the letting that agent go but it might be also your renovation quality.Hard to know without knowing the details.

Through COVID many state landlord laws changed and using something old off the internet could cause you issues if you need to take a tenant to court and have a lease that is not compliant with your law.
