As far as the business card is concerned, to me personally I think having both things on one business card is acceptable .  

Charge the late fee, a lot of people don't and that creates a relationship with the tenant that indicates to them that it is okay to pay late.

I haven't spoken to the county yet, but will make that phone call today.As far as financing -- I was leaning more towards getting a business line of credit or using a business credit card and rolling it over to interest free cards.

All this does is report their payments to the credit bureaus like how your credit cards or car loan company reports payments to the bureaus.  

I prefer to have the least amount of banks as possible.Create a bank account that you already have a relationship with(Credit card or mortgage)The least amount of bank accounts is also ideal.

This is not a one size fits all answer, but bad debt is non-asset based or depreciating assets - , credit cards, medical, buying dumb stuff.Good debt is debt used to make or grow your portfolio. 

For now, my immediate goal is to pay off all of my credit card debt (should be accomplished by February 1.), and continue to educate myself on NOI, Cap rate, cash-on -cash return etc.BP community, I am open-minded, willing to take initiative, always willing to be taught something new, but also ready to share any experience or knowledge I have that can help someone else. 

One powerful method is leveraging business credit cards to purchase and renovate properties at 0% interest and zero down payment.

All the add-ons are a la carte so you can definitely get a lot of value based on what you need.One thing I personally don't like is that when tenants pay rent, they are charged $1 per transaction for ACH use.

Here are some financing options to consider:HELOC or Cash-Out Refi on Another Property – If you or your mom have equity elsewhere, this could be a more flexible and lower-interest option.Business Line of Credit – Since the property is in an LLC, you might qualify for a business LOC, which could cover construction costs.Private Money Lender – If you’re okay with 12-15% rates, a private lender could fund this as a short-term loan, especially if the guesthouse will generate strong income.Construction Loan – Some lenders offer short-term construction financing, which converts to a longer-term mortgage once completed.Seller/Partner Financing – Bringing in an investor or structuring a joint venture with someone willing to fund the build in exchange for a share of the income.Credit Card Stacking or Unsecured Business Loans – Riskier but could work if you need to bridge a gap until the unit starts cash flowing.Would love to hear more details—especially your timeline and expected rental income.
