If your doing anything close to this tye property better be a 100% home run .Otherwise, we didn't do a portfolio loan until we had 5 houses and supporting tax returns and did everything cash up until then. i wouldn't do it until you have some track record before jumping into leverage and a heloc is made to use and pay off quickly.

And what are the future ramifications when withdrawing from the 401k since part of it should not be taxed?

Make sure the money you receive from rentals pays for all of your out-of-pocket costs, such as upkeep, insurance, taxes, and mortgage payments.Underestimating the Outlay: Add up all of the costs that come with owning and operating rental properties, such as capital expenditures, repairs, vacancies, and property management fees.

I like Tahoe Reno, NV market because of the appreciation growth, low taxes, landlord friendly, and constricted supply. 

You can write off expenses like taxes, insurance, etc.

I purchased a 1 BR 900sqft condo in 2021 with a depreciable tax basis of ~$275k and spent most of 2021 and first half of 2022 renovating the property (new appliances, flooring, painting, furniture, bathroom renovation, new kitchen countertops, new electric heaters, insulation, fireplace/pellet stove).

LLC has more tax treatment options (taxed as a sub S) and better protection than a land trust, if managed correctly.

This has been a side thing for us, and our accounting has been old school manual spreadsheets, along with rent collection varying from tenant to tenant (Zelle, PayPal, cash app, etc…) neither of us are great at keeping up with accounting which makes tax time a nightmare.

It is simply the IRS tax law.

Make sure that you have enough cash not only for the down payment, but also to cover the costs of closing, origination fees, property taxes, insurance and so on.
