Inventory seems low, and I am trying to househack my first unit.

Because, it's way too low. 

In some cases, federal tax credits like those for low-income housing or economic development might also apply if the project aligns with certain goals.Instead of buying the land outright, developers often lease it from the tribe, which can reduce upfront costs and sometimes come with favorable lease terms.

They said that was too low for them, so I offered $175,000 and they accepted. 

IF my numbers are truely "too low" I just looking gain confidence in how I am analyzing properties and estimating repairs.  1710 10TH AVE N, 37208: https://docs.google.com/spreadsheets/d/1B0CoSbGxQFbRBVzXBERw...6121 Southampton Dr 38119: https://docs.google.com/spreadsheets/d/1a3WBEcgv2SMggu5P2HrK...2014 Salem Mason Dr, 27208: https://docs.google.com/spreadsheets/d/1Jzr5TN9PYhuiFuD2THLb...Spoke with a seller yesterday, before I go with these numbers I thought it best to ask for some guidance. 

If my spouse wasn’t opposed to moving I would try to buy a new house hack every 12-15 months and use low down payment owner occupied loans for as long as it made sense.

But, it may not offer the ROI as other locales, and it may not be "fun" like buying in a favorite vacation spot.2 - The highest ROI folks - Self explanatory, will go where ROI is high and/or regulation low.3 - The second home/retirement minded - These people are looking for minimal ROI but want the house in a specific location because they like to use the property and want it to pay for itself.

No reserves, Income may be good, credit on the low side and NO Equity in the home.  

But you will never see the appreciation that truly builds wealth, because those low-barrier-to-entry properties will stay flat on the metric that matters: appreciation. 

In my area, they charge transfer tax on the assessed value rather than the LOW sale price.
