@Brett Wagner:
i deaigned my own spreadsheet for analyzing zing based on a few others I had seen. It changed over time to something that worked for me and I made different versions of it depending on whether I was looking to flip or make a rental. I downloaded one the other day from here at bigger pockets for free when I couldn’t locate mine on the computer I was using and I modified it slightly so I could see it the way I was familiar with seeing the results.
You can (and probably should) account for all of the little things that the analyzers have on there, but when you do, the numbers may get very thin. My friend who invests goes on less numbers and analysis and I need to see all of that to be comfortable. But she convinced me to back off of putting aside money each month on the analyzers for every little thing. Basically I just look to find a positive cash flow monthly of at least $300 and I would much rather that number be $500. My intention at that point is that if the place needs maintenance and capital repairs then that will have to come out of the cash flow numbers. Because in a very general way, that is what happens anyway. You will get into a place and get a renter in there and whether you are accounting for $100/ month for capital repairs and $50/month for maintenance, etc then a cash flow of $300... or you are looking at $450 of positive cash flow a month without accounting for those things, you are actually at the same place.
I do try and put back a significant amount of my positive cash flow until I’ve built up a comfortable savings before I allow myself to absorb he cash flow into my spendable money. And if I can live without it, I will put all of it back.
I have been pretty lucky I think so far in that costly repairs have been few and far between but I have built a cushion using the money from rents so I feel safe now that a repair would not (hopefully) end up digging into personal savings or turning into debt.
As for interest rates, I ask my lender friend what the current rates are and I buffet that a little just in case. Also, if you are planning a purchase where you will move in because you want to pay a lower down payment, the rate is lower for owner occupied loans... so if you are planning to turn it into a rental fast then you will be putting 20% down and paying a higher rate. So be sure and account for that.
Guessing rental rates is tricky. I do some research online. And if there are any rentals close by, I will call and inquire to get the best idea. Also Zillow let’s you look for properties as rentals and they have a rent estimate that you can go by roughly.
Rehab costs are difficult. If you are capable of doing work yourself then you likely have an idea of what is involved in the rehabbing process. There is a book available from bigger pockets that is about estimating rehab costs. It is very concise and helps you look at things you might not think about. I also got a book on doing home inspections so I could filollow along and kind of have an idea of what inspectors look at. Also helpful to know.
The book on buying rentals is very good. I have it as an audiobook and I listen to it repeatedly because each time I do, I see something new.
Hope that was helpful.
