Best,GZHello @Gabriel Zepeda,As @Andrew Abeyta correctly mentioned, there is not a direct and clean way to use 1031 exchanges to pay off debt on your existing portfolio.  1031s are great for lots of things, and they're really important to serious investors; however, they are not very useful as a tool for deleveraging. 

The exemption is applied to people that have lived in the house for 2 of the last 5 years. 

The tax exemption for Section 121 will not apply to the investment/rental portion. 

If the primary unit is over 15 years old, in most areas in CA the primary unit is now rent controlled (which I believe is not what was intended by the 15 year exemption but is the way most jurisdictions are applying the 15 year exemption).  

It is a bit of a gamble, but personally, I always get my own bids from people I will hire and either take a credit on price or have title issue the checks directly to those contractors to get work done as soon as I close.  

Windows need screens as far as I believe, but I've never heard of that applying to doors. 

We have found - from personal experience - that these courses offer general knowledge that often do not apply to your state or local area. 

Did you compare occupancy of properties not using platform bookings,all direct reservations ?

So, I will dispense this advise generally, as it can apply anywhere.

If you have some HTML experience you can also download templates to use directly in hubspot.
