If you don’t, maybe work with or for an existing company first for awhile?

You are considering putting a tiny home on your existing property as an ADU or using that money to save up and buy the next investment property and wondering which would be the wiser choice.I think ADUs can help provide additional, much needed, housing.

We approached the existing lender for a loan assumption.

Well, what would be happening is that your buyer would be buying your house subject to the existing note, since you can't legally sell the property without paying off that note or transferring the debt to the new buyer.

So we are committed to starting this journey. 

In your case, changing the property from a rental to your primary residence constitutes a change in use.The depreciation recapture will be calculated based on the fair market value of the building at the time of conversion, not including the land value.Since you're tearing down the existing structure, the entire amount of depreciation taken over the past two years will likely be recaptured, as the building's value at conversion will effectively be zero.The recaptured amount will be taxed as ordinary income, up to a maximum rate of 25% for residential rental property (Section 1250 property).

Think multi unit residential, commercial properties, or purchasing houses “subject to” existing mortgage.  

However, after receiving the survey results, I discovered that the house is located less than 1 foot over the sublot line (see attached image).Here are the options I’m considering:Rent the current house for market value (~$1,500–1,600/month) and convert the detached garage into an ADU to rent for ~$1,000/month.Relocate the house to split the lot, then sell the newly created lot (~$100,000) while renting out the existing house.Relocate the house to split the lot and build a new home on the second lot.Demolish the current house and garage, split the lot, and build two new homes.At this time, I am uncertain about the cost of relocating the house.Questions for the community:Has anyone faced a similar situation?

My understanding is an E2 Visa is an investor Visa (ie. you need to buy a business) OR you can piggyback off an existing E2 holder. 

A line of credit won’t commit you to a monthly payment unless you use the money, so you can avoid paying interest when it’s not in use.
