Others employ a BRRRR method or do wholesale deals/flips to have cash to invest long term. 

Your goal when renovating is to create a warm, comfortable and spacious environment.Typically this is done by using good lighting methods lighter colors with some sort of accent color and creating an open floor plan.For flooring, I would recommend using a lighter oak color.

Could it be interpreted that way, arguably yes.But if you're going to challenge a law's constitutionality, the reference I provided is perhaps the most common method.

This took away the LL capability to not renew lease or, my preferred method, provide large rent increase above market to get rid of less than ideal tenants.  

Consider that on many SFH with the BRRRR method you rent and hope to get a few hundred a month free and clear.

With rentals - it's cash flow every month for as long as you own it (presuming you find a good rental that cash flows - which isn't the easiest thing in today's market.)Know that you are coming into a high market - both real estate and money are expensive right now.  

I require all new tenants to use it, but I have a few that use other methods due to them being tenants when I acquired the properties.Background and credit checks are easy to send to an applicant - they pay 55.00 and I get the reports quickly. 

Only thing is other than personal finance, what other methods are there for funding, buy, rehab, rent out and hold type deals.

A lot of mistakes can be made if you do not talk to the right people and use preventive maintenance to avoid problems.Multifamily rentals are a great way to use the more doors more cash flow method.

I suppose one method would be to use seller reported figures but that wouldn't be prudent for many obvious reasons.
