In the winter I make the extra effort to advertise more places, and I sometimes offer incentives to encourage responses (e.g. discount on 2nd month's rent).

I paid $1138.80 (discounted rate) to get rid of those 7 tons via dumpsters.

It's a tremendous resource.  

@James DeRoestNew Equity can easily be created from buying property at discount, raising rents and making improvements.Principle payments is taking your cash and paying down debt.  

You will find this a tremendous resource for all of your real estate needs.

If you're using conventional financing you need to document 30% equity in your current primary that you're vacating in order to use 75% of gross rents from the tenant that will be renting your current home.You can document it by ordering an appraisal which is 450-700 dollars with rent survey attachment to the appraisal or you can sometimes do an AVM - automated valuation model which is usually free or a drive by appraisal with some banks which is usually 100-200 dollars.Some banks (portfolio non conventional) will all you to use gross rental income either discounted at 75% of face value or full 100% against your full PITIA (current residence) if you put down 20-25% on the new property.with FHA you can use gross rental income up to 85% of gross against PITIA when looknig to buy a new property assuming your current mortgage is not a FHA loan which you'd then have to adhere to 2nd primary/FHA rules/exceptions.You can see how these general questions on BP get answered so non nonchalantly however the depth of the answer really depends on your goals, your plans, and financing tools in use, and working with someone who actually understands not only the financing semantics and the investing objectives.

I let a friend stay in our rental for the last nine month for a discounted rent to get on his feet.

The concept of BRRRR is to acquire at deep discount, force equity through renovation, and then pull that equity by placing debt on the property.

The investor is making a one-time purchase (no volume discount) that is PRE-rehab. 

Tax sale rules vary tremendously from state to state.
