UK visitor visa without any property

Those don't seem to be required documents. Since you're asking for a visitor visa, according to their guidance: Visitor: supporting documents guide, the only required document is your passport and photo. For the supporting documents ("other documents you may want to provide"), it lists the following:

• Previous travel documents/passports, which show previous travel.
• Financial documents showing that you have sufficient funds available. These must clearly show that you have access to the funds, such as: bank statements, building society book, proof of earnings such as a letter from employer confirming employment details (start date of employment, salary, role, company contact details)
• where a third party (who is either in the UK or who will be legally in the UK at the time of your visit ) is providing financial support to you e.g. a business, a friend or a relative, documents to show they have sufficient resources to support you in addition to themselves and any dependant family should be provided
• Confirmation of legal residence, if you are not a national of the country in which you are applying or your right to reside there is not included in your passport.
• Details of employment or studies where you have stated in your application that you are either employed or in full-time studies. This could include: a letter from your employer on company headed paper, detailing your role, salary and length of employment, a letter from your education provider, on headed paper, confirming your enrolment and leave of absence.
• If self employed: business registration documents confirming the business owner’s name and the date the business started trading

Please note that this list doesn't even mention deeds or other evidence of property ownership!

Now, from personal experience: I know several Russians who got UK visitor visas while owning no real property. All however were employed with good income, traveled to other countries before, and were in their 30s.
