Thus the new strategy would rely on sourcing cash buyer investors who buy unseen and present those offers to FSBOs rather than just be listing holdover properties that are under indefinite tenant lockdown which is the gross new norm!

The excess loss is deferred i.e. carried over indefinitely until you have passive income available to utilize it against or you just sell your entire interest in this rental property.

I plan to put up to about $50k into rehab, which I can use a LOC for (and I can cash-flow those monthly payments from other income indefinitely if needed).

@Jonathan Felts, The 1031 would indefinitely defer paying the tax. 

If we decide to move long term and keep this plan going indefinitely, I think the added cost of putting in a kitchenette is a good one because based on my rough estimate from looking at sites like furnished finder, we could probably make $600-800 more by splitting the units. 

I'm struggling with figuring out a good way to purchase long-term rentals through traditional financing or BRRR using outside money that allows me to pay that investor back in a few years vs. indefinitely holding their principal and being a long-term partner.

If you use a personal car, make sure to keep a detailed record so that CPA can prorate the expenses between personal and business.

My ultimate goal is to have a portfolio of SFR rentals and just do some flips to get chunks of cash to buy more rentals, and I really intend to keep my current house as a rental indefinitely.

Like a car maker for instance.

- ^Assuming there's an indefinite timeline, how would I calculate the ROI on this?
