My goal is to buy 5 more rental properties this year and I plan to do so with the BRRRR strategy and when possible, buying turnkey properties with accumulated cash flow from my current rentals and profit from flipped properties. 

Trust me we all started with that 'one property' & many dropped out of REI simply because of that 'one property'.As you suck it up & continue to accumulate a larger portfolio there will always be that 'one property' that's the proverbial PITA.

That’s where the reserves I’ve been accumulating will come in handy.

You were not able to take any of the losses because your income was above $150,000.in 2017 - you have 7,000 of suspended losses and $1000 of loss generated in 2017.You sell the property for $125,000 and your adjusted basis is 78,400(21,600 of accumulated depreciation).You calculate 46,600 of gain but you are entitled to report the $8000 of losses on schedule E.Let me know if you have any questions.

You will accumulate from your cash flow to make a down payment for your next deal.

I wouldn't just tape those up.....Hard to tell on pix, but it may just be dust that is accumulating in areas due to normal air circulation/turbulence....if that's the case, you really just need to clean the unit up...... dust will kill the efficiency of cooling unitsWorst case is that its something liquid leaking and its blowing that material across that surface and dirt is sticking to thatBy sealing it up without knowing the issue, you are just encasing the issue out of site and will likely just postpone needing to deal with it.Id take the covers off and take  a better look....my gut is that's it dust material

Details - I pay 10,000 deposit to sign up, which I can earn back over the partnership, I also have to pay $397 a month. 1/3 deposit earned back on each deal we do1/3 back on accumulated marketing expensesWe have a 50/50 split on deals. 

But it's too much work for some people - you gotta know yourself.I used to have the same mindset as  @JD Martin until a family member flew him and 4 others half way around the world for like $300 in fees by accumulating points through the sign up bonuses. 

We have lived in West Seattle for ten years and have accumulated enough savings to buy our first investment property.
