If you don't delead it when you buy, you will have to when someone with a kids wants to rent it or when a tenant gets pregnant, so you might as well do it while you can get the seller to pay for some, or all of it, in negotiations. 

Many, many times I've used existing deposits that seller is supposed to give to me as part or all of a DP.

I would think you would set up a business account with one or all of the big 3 credit bureaus.

Hi Rafael, I grew up in the County and now live and work in the City, let me know if you ever have questions about locations in the City or all the different neighborhoods.

If you buy a duplex or multi-bedroom house, you could eliminate some or all of your mortgage/rent if you have full occupancy, maybe even some or all of your utilities/cable/internet if you play it correctly.

Or all the sites available to list an available rental.

generally speaking this would need to be done with either seller financing with release clauses or all cash .Major issues are going to be zoning and what can be done.. target props you like get feedback then go to the city or county whoever is the controlling agency and ask to talk to a planner this can usually be done over the counter will give you a quick look at what can and cannot be done. 

If you can do this by having a renter pay most or all of your living expenses while you live for free or close to it on a different floor you are setting yourself a solid foundation.

The whole point of going Airbnb over hotel is the kitchen for me, and I always end up with some kind of dull inadequate knife for cooking.

Is your goal based on retirement planning, tax savings, generational wealth, or all of the above?
