Hey everyone, what tools/method do you use for estimating the cost of maintenance and repairs of a multi-family home (2-4 units) ?

You also need UX, support, quality, a million other things.

From there, you can move on to the BRRRR method with single-family homes—buying undervalued properties, rehabbing them, renting them out, and refinancing to pull out your investment for the next deal.

@Rory DarcyRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Here is the Collin Hays method of buying the property at what you want to pay:Don’t ask the seller what their best offer is.

If you haven't connected with local people in your market there are several methods here.  

Perhaps a better vetting of the buyers on the BP side will enable better quality leads?

Key Check gave me credit and debt load, which was surprising, as most other methods people don't share.

This method offers greater efficiency, ease of use, and reliability.

@Cole Bossert I think @Sarah Kensinger and others have touched on the biggest qualities, especially communication.
