., I am not an economist and I can't predict the future, but I would look at the anticipated federal funds rate increases in 2022 as a starting point.

The airdna predictions in this market are off by a solid 10-20pct.

My concern though is this:  I think i can pretty closely pin down my expenses for this build and maintenance, but i'm not sure how to accurately predict revenue.  

@Patrick Senas I do not try to predict the price of RE in the short term as I think it is very difficult to do (and I have purchased twice near market highs so obviously I am not skilled enough to correctly predict short term prices every time).  

I can't predict market cycles. 

(they cut copper and wires)we put in to it 1 month of self work (learned from youtube) plus hired a professional (for the shower and kitchen) at total of 20k.we sold it just now for 35k (lost 7k)the good thing is that i can notice the mistakes:1. we've upgreaded the elctrical sistem at a bout 4k. most buyers dont care for that and it cause a lot of holes in the old plaster wall (much worse the dry wall)2. we didnt paint the outside- thinking it less important (its very important)3. we used stick on tiles instead of vinyl floor (1 days extra work), replaced windows that were old but not in a bad shape and a few more extras there and to littles here...4. to stress to buy (we were not local and had a flight back home) and to sell (we thought the snow slow the market down- its not so true)to summaries it:dont buy a house with electrical issues, bad windows, and rough exterior.dont be afraid from holes in the walls, old paint or pluming issues- those are reliability easy to fix and drop the purchase price dramatically.now we will buy 2 more houses with a purchase price of 12-20k, remodeling budget of 8-10k.we predicts a 15k profit on a flip and 20% roi on a rental (1 house for each niche)i leave you with some pictures

Knowing my luck if I went ahead and did that we'd get the "5% stock market pullback" that the everyone keeps predicting. 

People could predict a crash for decades before it happens.

Persistence is a good thing, but on the other hand,  you don't want to get so attached to the idea of this house that you're willing to buy it at a disadvantage to you (like without seeing it, or if it needs more work than you predicted, etc).

I hear time and time again from podcasts & advice online that this shouldn't be an excuse to pass on getting started (nobody can predict the future).
