My ideal financing solution would be for a hard money loan (~50% loan-to-value) with a required payback at either house sale or max 1 year.  

That being said, for clarification for anyone reading this, you are not required to notify the bank that title is transferring, it's perfectly legal when done the right way, if you do contact them they will call the loan due which they have a right to do but are not required to do, there are solutions if they do call the loan due.

Other solutions include "assuming the loan" formally, using Hard Money to refinance, working with the seller to make the bank happy, selling the property and several other solutions.

I have found my best deals off market and finding solutions for sellers.

Also had some very creative solutions that took more time but saved thousands of dollars.

Tools like Rentometer, Zillow, Cozy Rent Estimate, etc. are good - but rely on there being similar properties in the area.The best solution is to get a really good understanding of what your competition is renting their places for. 

Solution: maintain the formalities and keep the limited liability.- insurance company lawers will only represent individual not llc:  Insurance defense lawyers will protect the insured, regardless of the form that policy holder takes.- forced to use commercial loan, which has higher rates:  Depends on your situation. 

What other solutions are there?

So keeping it properly caulked will help, but the likely the only real solution would be to rebuild the shower pan and up the wall. 

When vetting your PMs, ask the questions that might provide solutions to these problems.Solution to #1 – you are looking for full transparency.
