Buyers should always do an inspection; it's a requirement in my private client firm. 

One thing I am finding is the reviews for some mentioned firms are all over the map.

CAn some one shed me some lights on how foreigner can invest in Duabi, which firms that I can go through, who are reliable and keep my investment safe and able to get some decent returns, and what are the tax consequences for earning potential from outside the country?

The marketing/advertising firm, aka RE broker, is not the expert in building codes, zoning, structural engineering, neighborhood safety, etc.As a prudent investor, always do your own due diligence or you'll end up being (unitentionally) misguided by a RE broker's information.  

Tell the tenant (with a firmly written notice) to fix or vacate.

Here are some important questions to ask when choosing a specialist.Does the firm have engineering licenses with the state authorities?

I am an attorney in New York and New Jersey and for the past 15 years worked my way up and became an owner/partner in a multi-state law firm.

I reply firmly that the rent has been late for the past two months as well as this month and she will have to vacate the property.Again, crickets...There are few days until the 10 day notice period expires and I can formally file for eviction.So I reached out to lawyers in the area and they ask for retainers up to $3k and some $300 consultation fees.

But if you have a cash buyer who is specifically looking for income property, and even more specifically a vacation rental property,  I firmly believe that there is a value add from having a working STR there.

I would invest in Sunrise Capital, but I didn't get the impression that they would accept $50K as an initial investment, which I always like to do to try out a new firm (for me) and to diversify geography and risk.
