@Will Pritchett It does count towards my income however the house hacking method mad it so I was only collecting rent from one unit for the majority of the year and after depreciating etc the property showed a loss.

Since this is being done within an LLC (as it should), and since there are different classes of membership interests (2 that I can ascertain), there are multiple factors to work out, some of which apply even when there's just one class of membership interest:How initial capital contributions, for each given class, are booked.How subsequent capital contributions, if any, for each given class, are booked.How member loans are booked.How each member's capital account will be handled pursuant to Treasury Regulation §1.704-1(b)(2)(iv), and how reevaluation of said accounts will take place per Treasury Regulation §1.704-1(b)(2)(iv)(f), to conform with §1.704-1(b)(2)(iv)(g).How distributions will be allocated, including profits and losses, along with any resulting adjustment of percentage interests.How tax allocations will be handled - and if the book value of any company property is adjusted per Treasury Regulation §1.704-3, how that affects member allocations.I have not even covered every item that must be addressed (including voting rights, depreciation allocation, cash flow vs liquidation allocations (as in "when we sell a property - who gets how much of the appreciation, but what about the recapture, etc, etc.")).Insufficient information... and it's time to meet my wife for dinner.

Not sure though.... should I profit from their loss, or am I doing them a service...

There is no appreciation in timeshares, so when you sell it you'll have a loss.

The nice part about it, if you're a borrower who discovers the loan you took was unlicensed, is that the maker becomes liable for repayment of the entire amount paid into the loan (principal and interest), in addition to the possible loss of the collateral interest in the property.The question to ask yourself, whenever someone says "you can probably get away with it if you limit the number of transactions you do" is... what are your morals?

Assuming you've already taken into account all of the expenses and losses that can happen (e.g. vacancy, repairs, capex) and that you've conservatively estimated them, I like to see over $200/month. 

The lender shouldn't have a problem with that, so I'm at a loss on that one.Get in touch with a local structural engineer familiar with old houses in the area like the one in question. 

You have a little net taxes early on - due to interest payment, but towards the end you get a break based on your capital loss.

Ultimately, the investor makes the decision based on their business model and tolerance for risk.Replacement Cost & Actual Cash Value loss settlement provisions and VERY importantly, how Co-Insurance affects your coverage are also two other pertinent things to consider when looking at coverage.One problem I will call out though is that so many of us are in such a hurry these days and professionals are less professional in many industries these days and are less about the relationship and more about churning numbers. 

That one might have a blockage from minerals, sediment etc and might not longer be effective and it appears to be a loss of water pressure when its really just a blocked up shower head.
