If you suspect that certain stipulations are being violated, then you have good grounds to make changes.

I just ordered 20 reports from a company and they missed on 2 (10% error rate) property sold at tax sale.Of course their “fine print” states they will only insure $1500 which I should of picked up that any company that has to stipulate a minimum coverage and not honor an errors and omissions clause for what the loss is, was a big red flag.

I am in a HOA that had some stipulations.

If the stipulation is that owner needs to live on premises, since an ADU would be a part of the primary residence, whether it is attached or not as it's on the same lot, I don't know that for the purpose of Short Term (Vacation) Rental it will make a difference, and seems it should be allowed.

I am in NH.I could resign a new 12 month lease.Go month to month.The lease stipulates that after 12 months it goes m2m.The deal here is I would like to remove this tenant.

What are the stipulations with going this route?

Unless the lending company stipulates something extremely specific, the governing body that cares about how you use the property is usually the State, County, local municipality and HOA (if applicable). 

You collect 100% on time or you charge late fees, file a 3-day Notice, or whatever your lease stipulates.

The primary restriction being that there can not be any lien applied or stipulated on or to the subject property.

Are there any stipulations with a HELOC  (i.e.: is a certain % of your mortgage required to be paid down before eligible,  or are you required to have had the mortgage for a certain period of time?
