Be conservative with your income and expenses calculations.

@Asiah PattonRun them through the calculators.

Since any renovations are unlikely to add value to the property, based on this discussion and thinking it through, I'm going to calculate ROI based on a 15 year holding period, looking at what reduces maintenance, risk, and helps keep rents at the level I want.  

If you don't have financials, you can calculate the expected NOI by multiplying the number of occupied spaces currently paying rent by the monthly lot rent, then multiply by 12 months, subtract the expenses, which can range from 30-50% depending on variables, so use 40% for your back of the napkin analysis.

Does the 1% rule apply here or is it a different calculation?

It is in my original calculation of $1,000 to change license with broker and $1,000 per transaction regardless of size ($100k or $1m). 

I'm able to put down 20% since house prices are much lower in that area, and I calculated ROI to be around 11% once the current tenant leaves and I'm able to get market rent. (9% with the current tenant) "Ok", I thought, "let's find out some actual financial numbers".I went through a loan company to get preapproved, and since my credit history is thin (I followed Dave Ramsey way too closely and didn't get a credit card until my senior year of college) my monthly payment is almost double what I was expecting.

I have a I have a duplex with heavy fire damage how I calculate the repair cost?

I need help calculating the repair cost for a fire damage duplex.

For example if I run the deal on the bigger pockets calculator and it looks good on paper how do I know that I will be able to put in a tenet?
