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

That could be 30-40% of the tax you would pay by just selling.But if you've really had  the intent to maybe hold this property for productive use and it's just not penciling out then you may want to think about a 1031 then or now if you end up selling and then buy your next hold property with financing that will let you keep it. 

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. 

The 10 year maturity date is where the LOC will modify into a different product all together.

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."

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.
