So if you have a property you occupy that appraises at $100,000, that means your annual taxes owed are $4,000? 

The reports are 40-90 pages long and go through the entire house in great detail.Get an appraisal.

@Adam Elbary: I can't speak to conventional lender requirements, but many private/HM lenders will be comfortable with less than 25% down... as long as you are buying the property below market/appraised value.

These are not all that common of features in the area (ADU's somewhat more so), and its hard to tell from the identifiable comps how the market might value them.Ultimately this is very usable space - but given an ultimate buyers appraisal may affect their ability to pay, we're trying to think through how an appraisal is likely to value these parts of the property. 

Though I will note that in my client's experience, Lima One moved a bit slower than most Hard Money / Private lenders as far as appraisal timelines and lending approval. 

@Adam David GraningThere are a lot of different guideline variances on these depending on the lender they go to and they've gotten much better than they were just a few years ago, but for the most part, you can get 75% cash out with rates in the 4's and low 5's on a 30 year fixed with no income verification.These loans carry a prepayment penalty, require all properties be appraised, require each property in the proposed portfolio to have a value of at least 75K and require the property to be stabilized (no renovation and leased). 

Agreed with the comment on the tax appraisal site numbers, they aren't always in line with market reality.  

Disclaimer: I'm not necessarily encouraging these routes, just saying they are options presented by the contract...Waiving the appraisal, waiving or shortening the inspection/"option" period, waiving financing contingencies, offering a seller's leaseback, buyer paying for title, offering a stronger earnest money, asking for fewer or even no repairs, and many more.Again, each state is particular, and some markets have trending "offer structures", so make sure to connect with an agent/lender in your local market to get a better read on the state of things and what you are capable of.  

In a market, I talk to as many vendors as I can - property managers, contractors, appraisers, realtors, etc.

Has anyone beat the appraisal district?
