Consider after the first year, converting 1 of the units to MTR.

Mortgage balances go down and eventually get paid off. 

For example, if market rent was $2,000, I might offer $1,900 and $1,950 for a 2-year lease to start.My leases convert to month-to-month at the end of the term.

I worked them, remodeled them and made very little money and eventually sold them for little to no profit.

Eventually it becomes second nature.

Xero will work since I have clients that uses them and well I helped them convert to it.

I would like to pass on a little bit of useful information for anybody thinking of converting their permit over to owner-builder. 1 - You will not be able to sell the property for a minimum of 365 days from the date of issuing of the CO. 2 - The property must be for the owner's own use and occupancy and not for sale or lease which means you will not be able to rent it out. 3 - The owner-builder must ensure that all employees working on the project have the required licenses.4 - The owner-builder must provide worker's compensation as required by Florida law.5 - To apply for the owner builder permit, you must physical visit the building department.There are others requirements and conditions, however these are the main items.

Rick, I am preparing to convert a detached garage in Anaheim into 2 bedroom ADU.  

Now is just one point in time and one can make permanent judgements based on the perceived current situation but that might be shortsighted.As far as the politics and legal framework, yeah it can be a pain, but for those who understand it, it eventually becomes a competitive advantage.

IDEALLY, we would like to find a property that has or is capable of being converted into a “mother in law”, “ADU”, “Casita”, or any other separate living quarters in which we could rent out the main portion to a tenant (short term or long term) and then use the separate space as our own for when we come and go with business.
