Hello BP community,I'm a landlord in California, and I'm dealing with a situation where my tenant is refusing to pay rent for the time during which mold repairs were being done due to water damage from a neighboring unit.

As long as your mom has the full down payment I don't think the bank will require you to put money as well.  

Thanks for the time in advance!

The due on sale clause will be the biggest worry, even though it's uncommon for banks to enforce it, they have the opportunity to at any time.

Generally, for the optimal refinance, these are top of mind for BRRRR strategy investors:Return of capital: The key “secret sauce” of the BRRRR method is to build portfolios using the same capital over and over—which relies on getting your basis (or more) back on the refinance, where basis refers to the money you invested in the property (down payment and cash used for renovations).Speed: Refinance lenders use the term “seasoning” to refer to the amount of time (typically in months) between the purchase of the property and the refinance.

Many times, I feel people project their own public speaking anxiety on me.

They always pay on time besides that. 

AS I have posted many times, why? 

Out of 282k how much taxes I have to pay right away and how much taxes I have to pay during end of tax year time.

It's okay if it takes some time to close.You can make your due diligence period shorter.
