One bad situation can harm all the properties.

There are situations where it is more beneficial to end the current lease and start a new one (ability to change lease terms, rent amount etc), and there are situations where it makes more sense to just do an addendum.

----------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

It's a very stressful situation for our team to keep having to contact you guys every month about our money.

Good luck on your journey and I hope you provide the financial security you hope for to your daughters.

The mortgage is currently under my name, so I’m unsure what benefits, if any, I’d gain from using an LLC in this situation.

The technicals (migration rates, job growth, tax situation, debt cost, etc) to work as well.
