Here are two models I’ve used in the past:
1% rent method. Basically evaluate the average rental cost in the area (apartments.com is what I use). Check for similar square footage, bedrooms, amenities, etc.
Is average rent cost for similar units is $3000/month, then 300k is a good price for the home.
If you can’t find a similar one in the area, hope on some public record sites and check the average income for the average family in the area. I shoot for around 33% rental cost of gross income (that’s what I’ve seen management companies use). So for example, if the average income is 72k/year that means a safe rent price would be $2000/month. This gives you the likelihood the average applicant could afford it.
Knowing $2000/month is a baseline, a good home value would be 200k.
monthly rent income = 1% home value
Method two is use a website like Zillow.com to check out the “sold” prices in the last year for the area. Remember to look at comps - similar square footage, yard, garage, bedrooms, etc.
These methods are a bit quick and dirty but can be effective to see if you should even consider a deal.
If you want to entertain it, decide if you want to whole sale it or buy and hold. A good risk mitigation technique is to find a price point that would cash flow if rented out. Then, using my income % method, if it rents for 2k/month, I would offer 150k-170k cash. This way, if I can’t sell it for profit, then I’m comfortable knowing I can profitably hold it.
Make sense? And keep in mind, without an agent, they are saving around 10%-13% in broker commissions, inspections, and possible alterations.
Hope this helps!
