The ease of structuring the Reverse 1031 Exchange will depend on whether it is an all cash purchase and whether there are any obstacles that would prevent the Qualified Intermediary from holding (parking) title to the acquired property. 

Let's say, for ease of calculations, that each is worth $250K.You also own your personal residence, which we can assume is worth $250K.Now, all of these are owned in your name.Let's say that one of your tenants trips and breaks her leg on your property.

Granted i only did 1 hot water line but i used sharkbite fittings, and yes they are a little costlier than than the standard copper fittings... but in my humble opinion the savings in time is well worth it... and for the record I have NO affiliation with this company.. just love the ease http://www.cashacme.com/prod_sharkbite.php

Are there any that would be more appropriate for this sort of scenario to ease “closing costs, etc…”Also, me and my BP are closing on a second REI tomorrow.

I have also put in vinyl plank flooring, which I like even better for durability and ease of installation, but it runs about 4x as much.  

Although, I do like @Kyle Foster out-of-the-box solution of just laying down 1/4" plywood to both level and ease the transition to the tile.

If you do own free and clear and are interested in seller financing, which seems to be what they are asking for, figure out a down payment requirement that would ease your mind if you have to take the house back from non-payment, high enough to cover any damages they've caused in the meantime.  

Keep in mind that if you below what the county assessor office values the property at, you can appeal the taxes and have them reduced with ease. 

Total scam........ they are often expensive, don't totally cover the items, the companies they use to "fix" claims are often crap and they will band aid the issue until the end of time......The single benefit is if you are OOS, you call them and they handle the claim, so you don't have to find your own repair people etc.....so its ease of use...... but you often have to manage the insurance company as they jerk you around, stall and band aid the actual issue.....Had one when I bought a rental in TX and then continued it when the initial expired..... regretted it to this day.I'll take one as part of the deal when I buy.... but wont keep paying for it myself.Better off building a network of repair companies you trust

There is also a program, a forgivable loan of $25k, to build an Adu to ease the housing crisis and keep rents moderate, basically pre-fab but no garage only an Adu...
