@Ethan Borshansky, There was a brief period of time in the early 2000s when this type of "leasehold exchange" as described above was fairly common. 

in my country real estate is not something that is so common,so was asking about the about the degree with the view that it would perhaps get me in track for real estate business.

Now they have exchanges, which are still not as secure as they are advertised to be by the operators. 

Thank you for your input.Keep a cheat sheet for your property(ies) with color brand/codes for each room and common info needed such as appliance info, fridge opening HxW, etc...Paint should be standard sets of colors for all the properties you have.Flat means hard to clean, repaint it all.

Now consider this: all the groups people are spending fortunes to target—foreclosures, absentee owners, probate leads, tax liens—what do they have in common?

DSCRs will have slightly higher rates and they also carry prepayment penalties, which kick in if you sell OR refinance the property within x number of years; 3-5 years is common. 

Common fees will include a set-up fee, a leasing fee for each turnover or a lease renewal fee, marking up maintenance, retaining late fees, and more.

Hey Denny - For rehab costs, a good place to start is breaking things down room by room and getting rough estimates for common repairs like the roof, HVAC, kitchen, light cosmetics, etc.

Providing a starter supply of items like laundry detergent, dryer sheets, and toiletries is common practice and works well for short stays.

@Paul Lucenti It is common to equate acquiring more properties to scaling and many rely on buying lower tier market/neighborhood section 8 rentals to achieve this goal.
