They are used for the brrr method.

What methods are working best for you?

Not super old, it will have some things wrong with it but the structure and plumbing should still have a lot of life left in them.

I would like to continue investing in the area using the BRRRR method and buy and hold after this house hack. 

As I've gathered, the terminology and methods have changed somewhat over the years. 

GREAT Topic,Make sure you know exactly what you want done on this home @ New floor coverings, new kitchen, counter tops, new lights, new bathroom fixtures.New paint , @ tone paint, etc, etc,Because  you holding on to it as a rental make sure you get at least 10 year materials and product, namely floors and plumbing faucets.  

Either way, the method of payment will not change the taxability of the repairs.  

If your realtor doesn't have a sophisticated system for querying the MLS a lower-tech method is to have the agent do a full CSV dump of the MLS for SFR and send it to you after stripping out the non-public data columns. 

@Albertinny Colin yeah, you can kind of see where all of these are going but the ENTIRE point of the BRRRR method is to reduce the out of pocket expense you have.  

I'm not sure that picking just one strategy is a good method, similar to what @Joe Villeneuve said.
