A mortgage lender can help determine if refinancing or tapping into equity might allow you to acquire additional properties.Consider a 1031 Exchange: If you're open to selling a current property, a 1031 exchange can defer capital gains taxes while enabling you to upgrade to a larger or more profitable asset.

Selling the property within your Solo 401(k) and returning the proceeds to the account simplifies compliance and ensures tax-deferred growth (or tax-free in a Roth Solo 401(k.)).

Will the property taxes skyrocket?

I don't claim to know everything and that is why I am here.

Finally, even as the landlords cash flow increases, depreciation should keep a major portion tax deferred. 

Sometimes they forget to tell you that many tenants in Detroit don't pay (depending on the property manager skill and the type of tenant) - but taxes are very high in the city and so is insurance. 

With the purchase, the rehab, the closing costs and the holding costs (hard money, taxes, insurance, utilities) our all in is around $200,000, but we have created $40,000 in equity.

Also 4th quarter of last year Packwood and county officially did discuss potentially regulating STR's by either limiting numbers or adding a tax to cover increases in local services that are needed. 

It can be done ethically, but you need safeguards to confirm mortgage & possibly property tax payments made on-time, as well as insurance with you protected.- Also, you need a legal way to take back the deed if buyer defaults!

It sucks for us LLs, because if the tenant is poor, LL won't go to small claims to get award, too, and then there's eventually no record.
