Is paying by cash a good idea for ~$2000 repairs as the contractor is offering ~6% discount.2.

I gave PM margin as discount to my tenant, to minimize vacancies.

I could imagine one way of making this happen: Buy five or more discounted properties for 20k or less, fix them and rent them, then refinance them after six months.

There are many opportunities out there to find good buys at a discount.

Do a market analysis and determine the value of each property and then put in your discount.

Instead of offering a discount on rent I'm thinking I could charge more since someone who smokes may think it's worth an extra $100/mo to not worry about breaking the rules.

I can get you a discount as a Florida Real Estate Broker..
