But for tax lien afaik it has to be done directly.Also I think tax lien should be done by professional or specialist in real estate due to unknown risk and regulation involved. 

Go after their real estate license by filing a complaint with your state regulator for this kind of licenses. 

Then...here come the regulators to downgrade the loan impacting the portfolio.

Stupid question but what does you state landlord tenant regulations say about rules and fines.To me fines, aside from late fees, seem rather childish.How do you prove who violated the rules.

You need to understand the tax regulations on both sides of the boarder.

You may not like all the taxes you pay, but you probably like the roads you drive on, the firefighters who put out your house when it catches on fire, police, schools, airports, football stadiums, regulations against poisons in toothpaste, and numerous, numerous other things the government does.Track down and work with a good accountant or tax strategist.

I'm searching for an insurance professional to discuss the concept of negotiating group purchasing property insurance for a discount (similar to what is done through health care via employers).Are there regulations that would make this prohibitively difficult in the property insurance industry?

The purpose of this regulation is to protect the integrity of the postal system and ensure that the USPS is compensated for its services.

@Rebecca ReadusWhen searching for a vacation home in Orlando with an in-law suite or ADU, consider the following factors: size and layout, zoning and regulations, separate entrances, kitchen and bathroom facilities, outdoor space, location, and budget.Size and layout should accommodate both living needs and potential rental space, with separate areas that could be converted into an ADU.
