That way you'll have custom tailored financing lined up when you're ready to pull the trigger on the next property.  

The owner is pointing to this line of the lease and stating that it is the tenant's responsibility to pay for the mold test after she reported that there may be an issue (as stated in the lease to report immediately).My question: who is responsible for the payment?

Thinking something aling the lines of a right to begin work clause?

That may vary by state law, but that's at least my line of thought. 

Under the list of "protected classes", the 10th line item is:"Source of Income The lawful source of a person’s income, including wages, a voucher having monetary value, social security, public assistance or other related payments."

I would think that would be your best bet.

Far better for me to position assets for them to benefit from at arms length than to saddle them with their dad's passion.Bottom line I am a huge fan of the 1031 used well. 

In many cases zoning has changed over time so that the property line setbacks and minimum lot sizes are much larger, which could render your lot useless for new construction. 

Can’t do it well without an open line of communication with the tenants or going to the property regularly.

They do research, have committees do tours of areas,etc.If you have her on a video chat you can look at how she responds to your questions when asking about time lines and getting back to you etc.
