A duplex or single-family home with an accessory dwelling unit (ADU) will let you have your own space while also offsetting your mortgage.

@Jaehan Kim Mainly just to obtain cash flow in all of my properties and eventually obtain the coveted financial independence.

In and around Seattle Single family homes with accessory dwelling units tend to have the best HouseHack ROI, followed by large single family homes rented by the room and true duplexes. 

For example converting the SFR into a duplex (through an Accessory Dwelling Unit or otherwise). 

Does anyone have any experience building an accessory dwelling unit in or around Saint Petersburg or the surrounding area? 

I'd fully anticipate the cost of this project to be around 300k all-in and I'm keen to understand how people are financing accessory dwelling units around the country, in California, and certainly in the bay area.I'm also very keen to understand how these ADUs are priced in a refi scenario.

The total cost for my 27' luxury geodome was around $88,800 (excluding land) and consists of the following step and costs:Zoning considerationsGeodome structure and accessories - $8,500Site preparation - $3,000Backfilling - $600Foundation - $3,000Decking material - $12,000Decking labor - $8,000Geodome construction labor - $4,200Flooring - $5,000Electrical wiring and labor - $5,000Interior wood divider - $2,500Hot tub - $13,000Furnishings - $10,000Miscellaneous costs and outdoor shower - $4,000The total costs for a geodome will range from a bare min of $25k to a max of $100k, depending on size, amenities and other factors like labor and material costs.Financing options include all cash, incorporating into a new house construction loan, SBA loans, or private money.

This is a great solution for anyone looking to refinance out of an FHA mortgage.Definition of limited cash out refinance:Client is not required to take any cash out but the maximum they can take out is the lessor of 1% of the loan amount or $2,000.Accessory Dwelling Units:Fannie Mae does not currently allow for the use of ADU’s on 2-4 units.

things like the 750,000$ tax deduction on mortgage interest on personal residences, or  your accumulation of wealth to the coveted "accredited investor" status. just like @Joseph Beilke said this should be hashed out with your lender, and if their not answering you out right they're probably trying to make a sell and keeping their a** covered at the same time. 

Hi Bernardo,Yes, landlords who are buying a used tiny home as an ADU (Accessory Dwelling Unit) in the Bonita area outside of San Diego will typically need to acquire permits before they can legally rent out the unit.The specific permit requirements and regulations can vary depending on the location and zoning of the property, as well as the specific details of the ADU.
