How much does it cost to buy down rate per %?

I just moved from Houston after living there for about a dozen years.

I’d even consider finishing the basement, just well enough for me to live down there, so I could rent out ALL the units.I’d save all my cash and look to refi the property in 1-2 years out of the FHA mortgage, so I could use it again if necessary.

For the 15 + years I’ve been on BP I’ve seen this reasoning, though there’s less of it in the last 5 years.

Verifying last 2 years of rental history very important!

Hopefully someone with tax accounting knowledge can jump in here with more detailed analysis, but I looked at this a bit several years ago...1) You still have to pay the depreciation recapture on the sale decreasing the net benefit of this approach due to the large tax payment in the 'sale' year2) The LLC would need to not be a passthrough entity so that it can be taxed separately from you, so you have to add another tax return cost for the years going ahead3) Taxing it separately from you likely means corporate status and corp. taxation rates which are higher than yours and I've heard many times over the years to avoid titling real property as a corp...Overall from what I've seen this only makes sense in a select few scenarios, which for most people aren't in play. 

I have been investing for years; stocks, options, bitcoin, real estate, and private lending and now I am getting out of all of it because my job is proving to have an infinitely higher return on time and it no longer makes financial sense to dump money into rentals. 

Eg (making up numbers) if a fridge lasts for 15 years, and they break a 10 year old fridge to the point it can't be repaired, you can only charge them 1/3 of the price of a new one as it had 5 years left.For the keys, if the ones she gave you don't work for the new locks, then charge her for a locksmith who will come by and re-key all of them. 

I saw in Charlotte Business journal that housing supply increased in January and continues to increase into February.  

Looking to get started.
