Not legal advice... but:
Here are two reason why I would not do it:
1.) If I registered your house/apartement on a company, I personally would
not register a vehicle on the same company because liability might arise from some incident with the car and the property or any other assets may be affected. In other words, I would like to keep any risk of liability away from the property... this is why I would have incorporated in the first place.
2.) People who keep real estate on companies tend to keep them as "clean" and worry free as possible. Keeping them away form liability issues being one reason for the practice, a clean company dedicated only to one piece of real estate also has the additional advantage to offer the possiblity to be sold all together with it's asset (in that case the mentioned property), herewith bypassing many fiscal transaction costs. But then, I do not know if that is comon practice in the DR.
(That being said, may I add on a side note, that I would be very cautious about buying an existing company because one not only buys the company's assets but also any pending liabilities even those not disclosed before!)
About the bank account: Some coutries' legislation requires a company to have a bank account in it's name... not just because companies do not have purses and pockets
. Usually some sort of formal accounting has to be filed with the authorities too, but again, I do not know how that is handled in the DR. Anyway, It makes things easier: You can "loan" money to your company... then that company will use that money to pay maintenance, phone and utility bills etc and other side handle any income from rental and so forth. In some cases VAT (sales tax can be balance out... but check that with your Dominican accountant!).
Anyway, this is in no way intended to be legal advice to you or anybody, it is just my personal opinion.
