Total time spent throughout the year may be significant, depending on the number of properties and amount of activities, but year end is no more difficult than any other time period they're doing. 

For example we invest in mortgage notes so we have an AI agent that only scans the documents we have and lists and if we asked a question like "who are our top rates attorneys in texas", it will give me the results vs. having to search files.

Every Week I scan the MLS, navigating cities and towns in South Florida that are friendly (and not friendly) toward short term rentals.

The way I interpret the following policy clause is that so long as the property is defined as other than "VACANT" which is the case when the property is being "constructed, altered or repaired", the 30-day time period and vacant status does not apply in this instance: We do not insure any loss at your premises if your dwelling has been vacant for more than 30 consecutive days immediately before the loss and the declaration page indicates an occupancy other than “VACANT“.

I do it myself and takes 20 to 30 minutes a month (did it yesterday for Dec), with about 7 of those minutes for 1 property in Blount County, TN which requires the form to be manually filled out, write a check, address an envelope, scan doc and check for my records and walk it to my mailbox.

You have to give a time period for him to fix or "cure" these violations.

However, there is no specific holding period contained in the tax code or regulations and there is no "safe harbor."

I saved up the cash over a 2yr period.
