If it appraises again for $93k and you have it under contract for $165k, they will only lend on $93k as a basis (so if you're putting 3.5% down, they will only lend you $89,745).

Do a little bit every day and over time you will see massive results. 

Otherwise it's on a case by case basis of the risk/reward with your specific tenant and what you're willing to offer them.

Analyze properties everyday, and show it to experienced investors to see what they think about the numbers. 

Since this is a percentage, it doesn't matter how much the property is, you will make the same amount on a percentage basis.

I offer my long-term rentals on a month-to-month basis for a 25% increase. $1,400 for a 3bed/2bath gets bumped to $1,750, then I add in the cost of utilities, TV, internet, and landscaping. 

An hourly billing model is common, however, I know a lot of tax pros that work with real estate investors bill on a non-hourly basis.

Cap rates have risen on STNL so in the 6's for cap rate and rates in the 3's you get almost a 275 basis point spread for return and can be passive.Retail centers lots of lenders have left the market and have little appetite for those properties.

Insurance Agents are licensed on a state by state basis so an agent in Charleston would be able to write a policy in Georgetown.

I love being fully immersed in RE everyday.
