There are some things you can potentialyl break out so make sure you have separate costs for materials/labor for:Land improvements, paint, flooring, appliances, blinds- there are few other more specific as wellA good REI Tax Strategist can help ensure you get the most benefit from your renovation

In addition to the original DMV titles, should I get a separate bill of sale for each unit? 

Originally posted by @Bruce Woodruff:Best way - Jackhammer it out and replace it, this time with adequate rebar and high pressure concrete.....Cheaper way - fill the cracks and paint it with deck paintCompromise - Lay tile on top (if you feel it's done moving) It's pretty uneven and separating. 

I would highly recommend setting aside the rental income in a separate account to build up a bit of a rainy day fund.

Are rest of utilities separately metered? 

Can I utilize the business bank account or would it be easier to have the funds separated personally since the income is technically not under the LLC?

However, if the duplex is “two separate 1/2 duplexes” each on a separate parcel/tax ID number, then no you can’t buy both with fha, period.

I also like one with a separate guest network so I can keep my smart home devices segregated.
