I do leave 6" solid oak or mahogany trim in historic buildings if it's in good shape but we paint or replace clam shell from the 50's and 60's.

I have each unit in the building with a unique rent rate, so even if the tenant does not have the teller enter a note with the deposit (they often do), I still know who the rent payment is from based on the amount. 

I own a business that builds modern, prefab tiny homes (or cabins depending on how you look at it), and I am looking for a market where I could set up a few of these to use as model homes, available as a STR.

I think that platforms, groups, etc. are only a small factor to vacacnies and slow periods. 

Currently, I'm focusing on building capital, saving, and investing to have more cash on hand until my next project, so for now, I'm simply educating myself on tax codes, financial investing, syndications, accounting, and creative ways to get involved in real estate investing. 

AKA it is a way to access some of the money you've put into your home while also making sure you can still afford your mortgage payments and other debts.You will need a renter in place as rental income is apart of the calculations when underwriting these loans in addition to the other factors you mentioned like monthly housing expenses (PITIA: principle, interest, taxes, insurance, assocaited fees ARV, debt outstanding.

I said I would be buying a 2-4 unit building not building a property.

My goal is to build a portfolio to hold and maintain for the long-term.

I will be doing this repeatedly to build my list of investment properties.

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23DSCR lenders generally let you vest either individually or as an LLC.
